I used scraps and a panel that was in my stash. Actually liked quilting the panel (3rd one) more than I thought I would!
I wasn't able to wash a charm pack before I used it so I ended up washing all three at the end (something I normally don't do).
The first one was a simple block pattern. The second was a pattern I kind of made up as I went along. The charms were 5x5...inside sashings were 2 1/2 and the outside white borders were 3 inches. The pink/yellow strips were 2 inches each.
These are simpler than I usually do because of the time constraints, but I really enjoyed them!
