Use them for "no-brainer" quilts - when you want to sew but don't want to have to think about pattern or layout. Simply put the pre-cuts together, add solid sashing and donate the finished top to a local quilt guild who could use it for a charity quilt. Either rows of blocks with sashing (self-cut or jelly roll strips), or put together into a large square then cut the large square into four triangles with diagonal slices and insert sashing or make 4-patch or 9-patch blocks surrounded by sashing.....whatever feels right
