Any piece of fabric that is 12" or larger can be used as a narrow border for a baby quilt cut into strips. I also sew the smaller pieces together for a crumb quilts, make doll quilts out of the small pieces, little girls don't care, all they want is something to wrap their baby with. Log cabin quilts are good to use to scraps. There are many ways to use scraps, just don't cut left overs until you are ready to use them. I also pin a small slip of paper onto the end of the quilt fabric that I have, that way I don't have to measure it, I already know how much fabric is in that piece.
