I cu t scraps into strips and squares. Strips should be 1 1/2 or 2 1/2 inches wide, but mostly, I cut into squares 2 1/2 x 2 1/2, 3 1/2 x 3 1/2, and 4 1/2 x 4 1/2. Anything larger than 4 1/2 x 4 1/2 gets put aside, and any odd size piece, or strip 1 inch or more (but not fitting the criteria for strips, as above) gets thrown in a bin for crumb blocks. Anything smaller than 1 inch goes in the trash can. Needless to say, not much goes in the trash. Right now, I've been cutting lots of 6 1/2 x 6 1/2 blocks for 18 inch square quilts for Threads of Love. It takes nine 6 1/2 x 6 1/2, 36 3 1/2 x 3 1/2, or 81 2 1/2 x 2/1/2 inch blocks for one 18 x 18 inch quilt. I sometimes use the 1 1/2 inch strips to make 6 1/2 x 6 1/2 inch blocks to use for the little quilts. I started Christmas theme quilts let week.
