Here is a little video I made of tying a glo bug yarn fly.
The main lesson here is just how to get the yarn to fluff on the hook.
Using this technique there is a million kinds of flies you can do.
You could start you fly with some kind of tail.
You can put hackle in between the first ball of yarn and the second.
You can trim the yarn into nice little balls with your scissors.
You can just do one ball
You can mix yarn colors.
You can put hackle or a tuft of white marabou on the head or you can come up with your own variations.
In the video I used four pieces of yarn the length of the hook shank.
I tie the yarn all together on the same side of the hook so there is more yarn on one side of the hook. I like to have the hook gap as free from yarn as I can get it. If there is too much yarn in the gap of the hook I will trim it with my scissors as the yarn does have the tendency to evenly go around the hook.
I prefer to have a messing looking bit of yarn because it looks like an egg cluster.
I am also going to show another step I use in another video as this is how I start the "Marks egg cluster fly".
So stay tuned.
