I have only joined in one swap and it was a blast. It was the blue and white star block swap. I was thrilled with every block I received-I loved the variety of stars and the shades of blue. Mostly what I loved about it was that each block I got was lovingly made by another member of this board.
I have not participated in any swaps since because I simply do not have the time. But I sure love looking at the swap results when everyone posts them on the board
