You know Jane I have been in swaps where all blocks were not perfect. To me the ideas of swaps is more than getting Prestine blocks, but the gift of friendship. As long as they did their best, I will love it. Remember we all don't have the same skill levels. I will take their imperfect block, for myself I am not perfect and will treasure it. If it honestly can't be used, it will in the bend with all the other blocks that were either off, extra, etc, and one day I will make a quilt with them all.
