RE: Round Robin Quilts!
I've "played" at this a couple times in my local Guild, and in a smaller group of friends. Choose your "block-mates" carefully. A number of us participated in a Baby Jane block swap. One of the group always waited until the last minute, and then tried to make up her own "shortcuts" in construction of the blocks. Unfortunately, these seldom worked, and I have about 20 blocks that I feel must be made over because of poor technique. Several of us face the same problem. She's got a heart of gold, but she just slaps her stuff together. I thought it was just me because I tend to be a perfectionist, but others have mentioned doing things over as well.
I've participated in a couple other groups where it was nearly impossible to tell the work of one from another. Just be sure to know the skill level of those you invite to participate. All that said, I'd do it again! It's fun to get together and swap the blocks.
