I find alot of precuts are not precut correctly so tend to stay away from them. Of course this was after I bought a bunch of it beforehand. I find Pat Speth's books uses precut 5" squares and cuts them to 4.5 x 5 so I've used my miscuts 5" as well as my 10 x 10 squares for her quilts. So far I've made 3 oversized lap quilts and am working on a full size quilt for myself using both sizes to rid myself of them. I'd rath cut my own yardage these days.
