I usually have a pattern that I want to do, so I pick fabric to make it out of. I'm not always successful with my selections, though, and I just love the look of the kits . . . all perfectly coordinated . . . I'm sure I'll be getting more than one as I progress in my quilting. I'm finding that I don't really like just buying fabric because I love the particular fabric. I can never decide what to do with it, so it doesn't get very far that way.
Enjoy your kits and show us some!
