Several years ago I participated in a Christmas paper-piecing exchange. Each person was responsible for completing 12 blocks, 11 of which were then sent to a coordinator, who in turn sent you back 11 blocks that others completed. I assembled the blocks into this small wall hanging. My block is the Christmas ornament, third row down in the middle.
I hope to do more exhanges like this as they are so much fun. If you know of any that will accept Canadian participants, please let me know.
