yes, I now use scraps down to the tinest scrap. make a pillow for your Humane Society, fill it with all the batting & fabric scraps. Sew shut. the animals love them & so do the workers. amazing how fast you can accumulate enough for a pillow.
I cut scraps into 1.5" strips for foundation block piecing and log cabins. make a jelly-roll out of these strips (sewed end to end). then make a log-cabin block around a bright middle. 10" squares make good charity quilts.
you don't match ends, just keep sewing on each side, trim, keep going.
I also cut 2.5" squares. I have made 2 big tops out of these. 2.5 strips & 3.5" strips are useful sizes. one of our quilters loves small sizes, so we give her anything over 1.5" that we don't want. she makes the nicest borders out of our scraps. don't get hung up on too many sizes.
I have found that cutting the scraps up into usable sizes right away is the easiest way to control them. if you need a leaf, etc, you can easily use one of the squares you have cut. with 20+years of quilting, I have seen a lot of scraps. elaine
