I participated in a swap years ago that was fun. We were supposed to end up with 12 blocks. We put a yard of focus fabric in a clean pizza box. Each month when we met, we’d swap boxes around and take a different box than we’d had before. We couldn’t sneak peeks in our boxes during the year, although some tried really hard to look! At the end of the year, we got our own box back with our completed 12” blocks. There were a few glitches, but mostly fun! The biggest glitch was folks not getting all their blocks. I only got 8, but that was ok. I made mine into a baby quilt and made the 9th block with my nephew’s name on it.
