Interesting using spray paint, but my experience with sheet wing materials and dryer sheets way back when is while they look great and catch fish, they don't fish as great.
They can tend to be heavy and sometimes cause flies to land "wrong" or cause a tippet to twist badly. In addition, because dryer sheets are unwoven, they will eventually begin to fray and fall apart and your pretty flies will look like a mess.
All of this pessimism is just a suggestion to first try making a FEW flies with dryer sheets and take them out for field trials before committing to tying up dozens.
