When I'm cutting out a quilt I keep any scraps intact that are at least 3" x 3". Everything else I cut into 1.5" or 2" squares and toss them into a basket I keep on my cutting table. I used 2500+ of these 1.5" squares to make my brother and sister-in-law a quilt (Irish Chain). The only problem I had was with the hand quilting because of all the seams. The quilt turned out very nice and VERY colorful.
