I have found the name brand precuts to be pretty accurate in measurements. But ones that have been cut by stores to sell as precuts tend to be off. I pretty much stick with the Modas, and others . I love Jenny Doan's tutes for speedy assembly of quilt tops. I have file cabinet drawers that are filled with layer cakes- 3, at least 4 drawers of jelly rolls, some are solids in one drawer, one drawer of batiks, and at least one more drawer with prints, and then another of charm squares. Then I have a file drawer filled with precuts I have cut from my scraps. Last year I made 43 quilts, most were lap size for charity gifting. This year my goal is just to use stash stash and more stash.

For me it varies with the type of pre-cut. Jelly rolls I keep together, unless they are "utility" rolls (all white, all black, etc.). Charms and layer cakes, though, always seem to have the nicest pattern on top. Unless you buy from MSQ, where you can see everything in the pack, you generally have a few duds in the group. I pull these out and cut them into smaller pieces a la Bonnie Hunter ("if it's still ugly, you didn't cut it small enough").

I couldn't do it, either. Too anal! LOL. I don't buy many precuts other than fat quarters which I store by color -- I don't often buy the fat quarter collections but when I did, I broke them up by just using out of them if I needed to. Currently I have 2 Moda Confetti charm packs which are so gorgeous I'm afraid I won't find the "right" quilt to use them in.

I like to pick up precuts when traveling and visiting Quilt shops in route. I keep them together. I have often used the Moda Layer Cakes for ideas and mindless sewing at Guild. I also check out Missouri Star for ideas and patterns.

Missouri Star has free patterns for charm packs (there was a super easy picnic quilt one a while ago I am wanting to try) … I would go to image.google.com jelly roll quilts for ideas too.

I bought a pretty sunny orange and yellow bundle of eighth yard cuts, and some extra fabric in a lemony yellow. Now I just need to figure out which pattern to use.

I too have a huge collection. My husband called me a fabric collector. He never saw my drawers full of precuts. Thanks goodness. I keep waiting patiently for the right pattern to jump out at me. Speaking of patterns I have a collection of those too.

Madamekelly, I’ve seen a quilt called Citrus Slice which could work for your yellow/orange fabric. Add some lime green for more variety!

It's an addiction, isn't it? We are curators of extensive textile collections. Since last year, I've been a follower of Gudrun Erla (gequiltdesigns.com). She came to Alaska to teach, and many of her patterns are based on precuts. In fact, she has a method of cutting her stash into increments she can use.

I tend to keep precuts together until I find the perfect pattern but not so with fat quarter bundles. Actually I don't have too many bundles but when I do I tend to either use them together or break them apart depending on what I'm going to do.
I'm also addicted to precuts! :)
