They are pretty rolled up, but I don't buy them. They never have enough of the fabric that caught my eye, and I usually won't use the rest. I have a friend who likes them, otherwise I'd be tossing the remainder out. I don't do strip quilts.
For instance:
I see a rust colored fabric I like - buy the roll, and there's only 2 strips of it. There are more rust strips but some are bluer, redder, or grayer, and don't go with what I want. So I prefer yardage.
Charms and fat quarters are a different story. They seem to be better coordinated. You can also check what's in the pack easier.
