I sort of scanned this thread, but there are any good number of books on fly tying. Yes it is old school, but they are usually broken down into sections which cover the basic techniques and materials. I learned most of what I know from books and trial and error. My point being, you can often find specific advice for your interest, or problems, without being overwhelmed. "The Fly Tying Bible, Production Fly Tying, and The Orvis Fly Pattern Index", are a few good ones IMO. I own several more, as well. Good luck. Oh, back to the topic, I just made a couple brook trout flies using foam for the wing. (Royal Coachman) You shape some packing foam with a scissors, tie it in place, and carefully split it with the scissors. Testing to follow.
