I sew totally get it. I just love looking at them. But, I am sooo starting to like using them also. lol

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.

I have purchased and used several jelly rolls, but I am NOT in love with them. Too often some fabric strips do not seem to work as well as the ones I have to substitute from my stash (or new purchase). They do look better rolled up though and are very decorative!

I will never buy Layer cakes again after trimming 3 packs all down to 9 1/2 squares due to none of them being 10x10. I have a few Jelly Rolls I haven't opened but let my DGD use one & I just loved all the colors & designs in it so maybe some day I'll actually open one up myself, Charm squares I've used a couple of times & they are usually pretty square.
