I do a lot of scrappy quilts, actually mostly scrappy ones. I try to cut the "scrap" to the biggest size I can, which means 1 1/2" squares for my postage stamp quilt, 2", 2 1/2" mostly, I also cut scrap fabrics to these "string" sizes- if possible, as well as charms. Anything bigger gets folded by color. I make LOTS of string quilts and crumb block quilts from the excess and use as much as I can, after that it goes into doggie beds. I am very lucky that my quilting friends gift me scraps- sometimes I trade their scraps for yardage if I have something they want! I prefer playing with scraps over yardage most of the time.
