This is the latest in Vanna's Choice yarn for the swap on Ravelry. It puckers somewhat fierce. AND, I did not stop at the 7 1/2 inches but continued the pattern so that it made a 12" square (I did improvise a bit). Turned out lovely, but the pucker started in the middle before I ever got past the 3rd row, so it is something inherent in the pattern she devised. I think it is that she did not have enough chains on the corners, so will try by making another one soon. Might keep this one myself as don't like passing on some of the more "disheveled" squares!
