i like tying in a clean area so i usually take out only enough material for the quantity of flies i'm going to tie and then throw away any type of leftover bits and trimmings. my goal is to not waste any material. not much you can do with 1/8 inch long butt ends of hackles or fallen guard hairs from spikey dubbing. whatever material i dont use goes back in the bag for future use on another hatch of flies
yup, i'm cheap
and damn proud of it!
