Using that model I had what I believed to be the perfect material to use for that egg sac. It came in a box of shoes Kyla ordered online. Some black semi-transparent foam was used as packing material for the shoes and it had a lot of bubbly pattern to it. My first try I didn't put much of a head on the fly and here is what I came up with:
I liked the basic concept but with a foam tail this fly is going to need more buoyancy in the head to float good and level. I then tied it with a bullet head and liked the results much better:
Now all that remains is a good test run with a handful of patterns come March.
