Take all the tieing stuff and place it neatly in order on the table, then take one of your size 15's and proceed to beat the hell out of the stuff
I have size 14 and I don't think that my huge hands and fingers have anything to do with having trouble tieing tailhooks. I just think I don't have the patience for them to come out perfect like you expect also. Did you try putting the hair on in 2 or 3 clumps not just one big clump all at once?
good luck
