I started cutting a lot of my scraps into 1 1/2, 2, 2 1/2, 3 inch and so on. I saved mixed greens containers from the produce dept. and have them nicely lined up on a shelf. When I was making charity place mats for Meals on Wheels, I just grabbed a handful of already cut squares and sewed them together randomly. What I like about the size increments is that I can use the 3 inch size to make HST's to put with the 2 inch (finished) size so I have more options.
