Oh dear, Barb... that's the thing about mystery quilts. You just never know what you are going to get. Now I'm really curious to see how you fix it. Please do show pictures when you get it together.
I did a small mystery quilt on New Year's Day with the Quiltbug.com site... didn't really love the pattern on that, either. I used a roll of I Spy strips I got in a swap and once it was quilted it did look cute. Some child will enjoy it, I'm sure.
Bonnie Hunter's latest mystery quilt turned out beautifully, but the one she did last year was a real disappointment to many of the people who made it. You just never know.
