I cut 2.5 inch strips only. My smaller scraps I cut 7.5 inches long. If I have the end of a yard cut I leave the strip full length. Everything smaller goes in the garbage, I like to buy fabric to much to hang onto anything smaller and actually use it up in a scrap quilt. If I were to keep anything smaller with the intention to use it in a scrap quilt, I'd just end up with baskets of small scraps. I then make friendship braid strips and add sashing to make a quilt or some variation of a log cabin block with my 2.5" scraps. I find this is what works for me. I also do paper piecing so have odd shaped scraps and have made QAYG wonky blocks, but didn't really enjoy it, they looked good, but the technique didn't appeal to me, so now I pass those types of scraps on for someone else to use.
