I use the large plastic buckets that cat litter comes in (I get it at Sams)..I had labels on each of them, with colors and I put all my 4" squares in them.......when one gets full, I know I have enough to do a quilt, in whatever color it holds. (these are the left overs, cut to square size)> I also use the cookie plastic tubs from Sams, to put the smaller cut scrap squares in.........they have lids too, so labels for 2", 3",etc.........and they stack, with the lids on.I have my small scissors tied to a long ribbon, and that is tied to the drawer pull on the sewing machine (always dropping it, now I can pull it back easily).I use one of those litter buckets beside the machine, to catch all the scrap pieces in, and then I go back later and cut them to usable sizes. I also have a bucket for "strings" size pieces.
