When I finish a quilt I cut up the leftover scraps "not" large enough to use for another project into squares from 1 3/4" to 4 1/4" and store them in photo boxes labeled with the size of the squares. Therefore when I (for some unusual reason) need squares of any of these sizes I have a box to go through. Right now I'm making a scrapy 4 patch from a box full of 2 1/2" squares. Looks as if it's going to be a right nice size quilt.
