I just came across this video and found it helpful for when you want to use those bigger feathers for your soft hackle flies. Thought others might too.
Toshirou Todoroki showed me this method
Thanks Tristan. I was running out of smaller leathers and was wondering what I was going to do with all the too-large feathers.
I saw something like this before, and adapted it to my tying by starting with a very small plastic bead at the eye (red or black, depending) and when I wrap the thread forward over the hackle it makes it stand out perfectly. Tight thread wraps for a 90° angle, gentle wraps for a reverse hackle.
