interesting topic. I keep bundles together in one drawer. I save 2.5, 2, and 1.5 inch strips. they are in 3 different containers or drawers. however if I have a bunch of one color say I have teal 2.5 inch strips leftover from a project I will put those in a plastic ziplock or similar bag and then add that to my 2.5 inch drawer.
Thanks everyone for ideas. it's a never ending work in process for me.
