Here is a step by step, on how i tie my snake flies.

Some materials that you will need.

Thread mono braid back in side it's self.

Here both ends ends have been threaded, i am using a size 14 swivel head of fly and a size 6 treble.

Here are the tools i use for threading mono braid.
Here the braid has been pulled tight, and a tiny drop of super glue to lock braid. here do not put a lot of glue as it will run up braid and make mount stiff. the mount for this fly should be nice and flexi.

Next thread shrink tube over mount, i use a boillie needle to do this,

Here you see tools i use for pulling shrink tube over braid mount.

Here you see shrink tube on mount after steaming with kettle, and before steaming. the size i use is 2.2mm.

Now place hook in vice, and add flash if need be.

Now here i have opened mylar piping to give fly add flash, and whip in butt of fly.

Here mount is finished, note i have a few turns behind eye of swivel to hold mylar.

Now i have put three coats of sally hanson mega shine leave to dry.

Here are a few i have done with single hooks, and also with loop at head of fly. some of my customers that i tie for like loop at head of fly so that they can add cone's for heavy water in rivers or deep pools.

Here a tip for those who dont have lot of color mylar, use colored braid with pearl mylar and the color of braid core will show though pearl. plus it does give off a nice glow when wet. or white braid and color with high lighter pen.

Now this is the bit a lot don't like, you have to tie wing on in you hand. it can be a pain when you start, but practice will get you there.

And here is the finished fly for this step by step. tie in with some Amherst neck feather and some jungle cock.

And this is the hair i like to use for my snake flies, Marble fox. which i tie up for sewin/sea trout, salmon and bass flies.
