For a time, I had a ball doing swaps.......really met a lot of fun people "on board". But there were some really undependable folks on the last one I did which really wasn't fair to many. They took their turn, but didn't return the favor to other's.
I do have a lot of swap blocks to finish into tops and doubt I will enter swaps again.......partly because of the postage involved and partly because I am responsible and I have a hard time with those who are not... :(
