I do think pre-cutting helps reduce stash. When you have a number of strips ready to go it is easy to grab some and start sewing. I have started pre-cutting a group of "co-ordinated" fabrics. I pull together a group which has lights darks and mediums and cut 2.5 strips. Do not worry about the "subjects" of the fabric, just look at value. These are great for jelly-roll tops or for bordering other blocks. It also works great for kits, it you have someone in your quilting group or friends circle, who will sew but is intimidated by trying to put together enough fabric for a quilt top. I love, love love the Accuquilt strip cutters. I also use the 6" block for D9p tops.
