In the way of precuts, I have primarily purchased 5 inch charm packs. However, my intent for them is to make charm-style quilts - that is, quilts with no repeating fabrics. With that in mind, I usually split my charm packs quickly into bins (the deep ArtBin containers with dividers) by light/medium/dark and color. The only 2.5 inch strip packs I've purchased have almost immediately been made into quilt tops. I think I'd find it more of a challenge to split those up.
