I made hydropsyche larvas with your bodies with hooks. The result is great, to tie them is almost too easy.
I also made several stone fly nymphs. They look spectacular. You have to be very precise to make them.
I used your wings on big dry mayfly. It looks very good.
I still have to use them in the Eastern Siera in California and on Kyll river in Germany.
I hope they catch lot of fish.
I thank you for the beautiful patterns.
