I have two containers on my cutting table; one if for really small threads of materials the other is for larger scraps that aren't large enough to cut into squares. I take the small stuff and dump it into a bag and then if I want to stuff a toy or something I can use it. I use the larger stuff for applique; you'd be surprised how small a scrap can be and still be good for applique. For the small stuff;it doesn't matter what type of material it is.
