I usually don't buy precuts(due to price) but I will when i need a lot of variety. For ex., DD wanted a quilt from all B and W prints. by the time i would have bought enough different prints and cut them myself, the cost of buying precuts -in this case jellyrolls-looked pretty good. i also will buy charm packs if i find them at a good price, just to have a variety on hand for a quick baby quilt. I usually pair them with solids from my stash.
