although I'm not participating in this swap, I've been watching. What I found for the blocks I've received, I've laid them out, and made "families"- ones that look good together. If I received an odd sized one, I separate it from the others and then pinned them together, hoping I end up with three. These become a table runner. The b&y blocks ended up as 2 different sets- ones that played true blue and yellow, and one that had florals. (Oh, I made 3 sets- that's why I had so many to play with.)
I learned a lot along the way- how to make my blocks measure up, but I'm still working on my accuracy to points not disappearing in the seams. I continue to strive to be more accurate as I continue quilting.
