I do not swap blocks.
The first time I did a block swap (on a different board)
I was extremely disappointed.
Several blocks were smaller than the size they were suppose to be. Several didn't follow the color placement the block called for. Which was really important in this block for the overall look of the finished quilt. And I had a couple blocks the fabric was thinner than a tissue and would not have held up to washing.
Out of 14 blocks I could use only 6 blocks.
Because of the disappointment decided then and there never to do another swap. :cry:
