I sort them by color and keep in gallon sized zip looks. Periodically, I will spend 30 or 45 minutes a day cutting some into squares or strips. That is when I get rid of the bits that cannot be used. I use them with fiber fluff and shredded batting for stuffing critters, etc. It works great. I try to stuff the mixture in the center of things and use the fiber fluff nearer the outside of the project which I want as smooth as possible. I learned this trick from a quilt guild that made critters and blankets for kids.
