Tying Instructions by Tom Sheehy

 
Background

My first introduction to the Crease Fly was from a fly-swap I participated in about six years ago.  As I remember it, there were about a dozen flies in the swap, and as you would expect, most of them were simple variations of clousers or deceivers.  The one fly that really stood out from the crowd was a beautifully painted blue over silver Crease Fly.  

At the time, I had never seen anything like it, and was really impressed by the way it looked and behaved in the water.  It was so nice looking, in fact, that I didn't want to lose it or have it get all beat up catching schoolies, so it was relegated to the backup fly box.

Subconsciously, there was another reason I shelved that fly.  Those of you that have fished with me may know that I very rarely use someone else's fly -- for the simple reason that I would hate to catch "the big one" on something that I hadn't tied myself.  Even if someone is out-fishing me ten to one, I'll refuse the hot fly of the day and try to find something in my box which will work.  I realize that this is a ridiculous philosophy, because you can guarantee that I will be back in the same spot the next day, casting an exact replica of that same fly that I tied up the night before.

About a year and a half after the fly swap, I was having one of those 'kitchen sink' days out in my canoe on Joppa Flats in Newburyport.  It was a perfect evening in late June, with the smallest breeze to keep the no-see-ums away, and fish were all over the flat.  No matter where I went, I was spooking fish and would occasionally set off a huge chain reaction of one school spooking another and another.  The problem was, I was throwing everything but the kitchen sink at them and couldn't buy a bite.  After about an hour of complete frustration and literally throwing everything I had at them, I decided to tie on the one fly in the box that I hadn't tied myself, that beautiful blue and silver Crease Fly.

You can probably guess the outcome of the story at this point:  I managed to pick up quite a few nice fish that night, all on the Crease Fly.  So many, in fact, that it got completely destroyed in the process, but I went home a very happy camper.

Back then, I couldn't find any of these flies in the local shops, and none of them carried the foam that was needed to tie my own.  Over the remainder of that season and the following winter, I had completely forgotten about that great night with the Crease Fly.

Over the last several years, the Crease Fly has become increasingly popular, has been featured in a number of magazines and internet sites, and is even being sold in some fly shops.  It was also featured in Bob Veverka's Innovative Saltwater Flies along with an introduction and background from its creator, Capt. Joe Blados, who lives and fishes on Long Island. 

This past fall I was re-introduced to the Crease Fly through a friend who was having great luck with them from shore.  I quickly ordered the materials I needed for this fly and managed to have a couple good days of fishing with them before the fish headed south.  Now that the fish have left, I have been refining the pattern and trying different methods and materials to create it.  

The Crease Fly is certainly very easy to tie, once you understand the basic concepts involved, and I'm sure that experienced tiers won't have to read through the gory details to figure it out.  What I do hope to accomplish through this guide is to help cut down the learning curve for the beginning and intermediate tiers by sharing what I have learned this far.

Tying Instructions

First and foremost, it should be noted that the Crease Fly isn't really a specific pattern.  It is much more of a technique that can be used to create a number of different patterns, simply by using different materials, baitfish profiles and coloration.  I have seen many different sizes and colors of Crease Flies, some that had foam bodies that were at least six inches long, others that were tied in a 'broken back' style where the body was separated into two halves and joined in the middle to increase the action of the fly.

Several fly shops have started carrying Crease Fly kits which provide all the materials you need to create this great fly:  several sheets of foam in various colors, a bottle of CA (superglue) and several sheets of mylar foil which are used to color the foam.  It is also one of the few readily available sources of the adhesive backed foam that can be used in one method of decorating crease flies, which I will explain below.

If you have been tying for a while you know how much of a difference the right materials can make, and even though the Crease Fly is a simple pattern, it can be made much more complicated by not using the right types of foam or superglue, as I will describe in the tying instructions.  In any case, I highly recommend this kit as a great way to get started -- it provides all the 'right stuff' that you need and is very reasonably priced.  

Step 1

The first thing to do is to select the proper hook. Any long-shanked hook will do, the longer the better. You want a hook that will give you enough room to duplicate the size of the baitfish you are trying to imitate while still giving you a nice wide hook gap to work with.  Some of the hooks that I have used are the Mustad 34011, the Tiemco 511S and the Tiemco 911S.

My first choice would be the Tiemco 511S. This is a stainless popper hook that has a 4X long shank with a 2X wide hook gap, and a mid-shank hump which increases the surface area you have to glue the foam to the hook.

Since the Tiemco 511S is sometimes hard to come by, I am using a size 1/0 Tiemco 911S in this example. The 911S is also a stainless hook with a 4X long shank, but with a standard gap.

The first step is to cover the entire hook shank with a nice base of thread.  In most of my tying, I have switched to using mono thread, but in this application I believe that standard thread makes a better foundation to accept the glue and hold the fly together.

Step 2

Next, you will tie in the tail materials.  As you would expect, most tiers use a darker color over some flash and a white base.  You can use anything you want to create the tail:  bucktail, ultra-hair, whatever you have handy.  The important thing is to think ahead a few steps and determine how you are going to finish off and color the foam body of the fly, then make sure you pick a tail color that will match.

In this picture, I have tied in some white Kinky Fiber with some pearl Flashabou on top.  You want the length of the tail to match the general length of the baitfish you are trying to copy.  I find that a length of one to one and a half hook shanks looks best.

Step 3

Here, I have completed the tail section by tying in some light olive Kinky Fiber.  Again, you can use any colors or materials that you want.  I chose this color scheme to match the finished look of the foam body.

Once you have tied in the tail materials, make sure that the hook shank is completely covered in thread, and then tie off with a whip finish.  At this point you have done all the 'tying' involved in making a Crease Fly - the rest of it is more like an arts and crafts project.

Step 4

The next step is to create the foam body of the fly.  There are many ways that you can come up with the right shape or profile to the foam body. The simplest method is to just cut yourself a piece of foam and slowly modify it until you get a shape that you like.  However I have found that if I don't start with a plan, I very rarely come out with something that I am satisfied with.  I learned this very quickly after painstakingly hacking to pieces several nice stacked deer hair bass bug heads.  

If you do take this approach, make sure to fold the foam in half and cut out the profile for both sides of the body at the same time to make sure they are symmetrical - then skip down to Step 10.

What I found to work best was to start with a piece of scrap paper, and to sketch out a pattern that I could size and trim without wasting a lot of foam.  In the picture above, I have created a rectangle that is as long as the distance between the hook eye and the bend, and is as wide as the gap of the hook.  This is a good starting point to get the proportions right until you feel more comfortable creating your own designs.

Step 5

Once you have the basic rectangle defined, fold the paper in half in line with the top of the rectangle, and cut out the other three sides of the rectangle.  You want to end up with a tent of paper which is connected along the top of the long sides.  The walls of the tent will be the size of the rectangle you created in Step 4.

Next you can start sketching out the basic profile of the fly on the paper.  You can make the shape as simple or as complicated as you want- just keep in mind a few basic ideas:

  • You want to keep the hook at the very bottom of the body in order for it to act as a keel and keep the fly upright when it is in the water.
  • Try and keep the front edge of the body perpendicular to the hook shank.  This will allow the fly to track through the water much straighter.  If you angle the front of the head, the fly may twist and spin as you retrieve it.
  • Try to find a profile that represents the baitfish you are trying to copy, but also maximizes the amount of space between the foam body and the hook point.  If the body crowds the hook point, you won't have a big enough gap to actually hook any fish.

You can angle the template as you see fit to alter the profile of the body.  In the picture I have angled the template to create a big 'mouth' on the fly, but have drawn in dashed lines to make sure that the face of the body is perpendicular to the hook, and to create a wide body with plenty of space at the hook gap.

Step 7

In this step I have cut out the basic outline of the body and have fitted it over the hook to make sure that I am happy with the proportions, hook gap, and alignment.  The eye of the hook is at the lower right hand corner of the template.

Step 8

The nice thing about using a paper template is that once you find a shape you like, you can quickly reproduce it and use it as a pattern.  This picture shows the body template after it has been unfolded, along with a couple of different bodies that I had cut from a master pattern. (marked with a 'M' to make sure I don't use it)  You will also notice that I typically cut a small notch out of the back of the fly for the tail to pass through.

Step 9

In this picture you can see the foam body that was cut using the template as a guide.  

Step 10

This picture shows the flip side of the foam body, which has already been coated with a metallic mylar film.  This is another area where you have many techniques to choose from in order to color the foam body.

The simplest method is to use plain white foam for the body and waterproof markers to provide the coloration.  Try experimenting with different color combinations, and layering multiple colors on top of one another to blend them together and get the desired effect.  You can also use a metallic chrome paint marker to dress up the body and provide additional flash.

Another method is to use the plain white foam along with fabric paints or EZ Sparkle Body to provide the coloration and flash.  The EZ Sparkle Body paints are very easy to apply, and contain glitter to really make the fly stand out.  One of my favorite patterns uses white pearl for the body, with a dark olive and black topping.  Blood red sparkle body is used to provide a bleeding gill effect.

If you choose to get the Crease Fly kit, you will also get a couple of sheets of adhesive backed foam and several sheets of metallic foil.  The foil has a plastic covering on one side.  Once the protective covering is removed from the foam, it will then stick to the metal foil.

There are at least two ways to use the adhesive backed foam.  The first way is to cut out and attach the foam body of the fly with the protective covering still in place, so that when the fly is finished, you remove the covering, which exposes the adhesive on the outside of the fly.  You can then press the fly into the foil sheet and it will pick up the foil, leaving the plastic coating of the foil behind.  This can be tricky to get a uniform foil coating throughout the entire body, but if you find a spot that didn't stick, you can just keep pressing it into the foil until it is covered.  This sounds more complicated than it really is - it will make much more sense once you have the materials in front of you.

This method also lets you create more complex designs by using different color foils to cover different areas of the fly.  For example to create a fly with a metallic blue back and silver sides, you would roll the top of the fly in the blue foil until it was coated the way you wanted, and would then press the flat sides of the body into the silver foil.

The other way to use the adhesive backed foam is to take a whole sheet of foam, remove the adhesive backing and carefully apply a whole sheet of metallic foil to it, being careful not to get any air bubbles trapped underneath the foil.

This is the method that I happened to use in the foam body for this fly.  In the picture I have flipped over the foam body showing the silver foil that has already been glued to the back.  A good tip here is to leave the plastic protective covering on the foil until the fly has been completed.  This way you won't get any superglue on it, or otherwise damage its appearance while you are gluing the body in place.

Step 11

The next step is to start gluing the foam body in place.  This is another very good reason to start with the Crease Fly kit.  It comes with a specific type of thick CA which is made by a company called Balsa USA.  I have always assumed that all superglues were created equal.  When I received my kit, I already had three or four bottles of superglues in different thicknesses and from different companies.  I found that these other glues took much longer to set up, and made gluing the foam body together a much more tedious and messy process.

The thick CA from Balsa USA works much better, and much quicker than the other superglues that I have tried.  The best technique is to start at the hook eye, and slowly glue the foam together, working your way towards the bend of the hook.  I have found that it is very difficult to glue the entire body together in one shot, because  you quickly run out of fingers to clamp the body together while the glue sets up.

After making sure the foam is positioned correctly on the hook, apply a few very small drops to the foam while holding it together with the thumb and index finger of one hand.  The more glue you apply, the longer it will take to set, and trust me, you don't need very much to make a very strong bond which will be much stronger than the foam itself.  Once you have applied a couple small drops of glue, pinch the sides of the foam against the hook shank while the glue sets up.  It should only take five to ten seconds if you have used the right amount of glue.

You also want to make sure that you don't use so much glue that it wicks up into the body of the fly, and glues the sides of the body together.

Step 12

Continue working your way down towards the tail of the fly, making sure that you have a good solid joint between the foam and the hook.  Once you get to the tail section, you can use a little more glue around the tail material to hold it in place.

Step 13

At this point, the fly is nearly complete.  The next thing to do, once the superglue has set up properly, is to push down on the top of the foam to make sure you have a nice wide opening.

In this picture I have colored the front of the fly with a red marker to make it easier to see while fishing, and to illustrate the proper shape for the body.

Step 14

The last step is to finish coloring the fly using waterproof markers, EZ Sparkle Body or whatever else you can come up with.

In this example I was using the white adhesive-backed foam with the metallic foil already applied.  Once the body was glued onto the hook, I peeled the protective plastic covering off the foil, and used green and red markers to color the back of the fly and draw in some gills.

The last step was to apply some mylar prismatic eyes and to coat the entire body and mouth of the fly with Loon Hard Head.  You can also use a thin coat of epoxy to get a similar effect, but I have found the Hard Head is very easy to apply and produces a very nice finish without all the mess and odor of epoxy.

Don't forget to coat the bottom and the mouth of the fly to make sure it maintains the correct shape.


As you can imagine, there are no limits to the number of sizes, shapes and colors that you can create.  The Crease Fly in the above left picture was created using a metallic gold foil for the body and black marker for the back. The fly on the left used pearl EZ Sparkle Body for the body, olive and black for the back, and red for the gills.

If you've been patient enough to read through this entire long-winded set of instructions, I'm sure you won't have any problems creating crease flies on your own.  I know that I am very anxious to throw some of my new creations at that first big push of fish which shows up on the Merrimack next May.
