Arwen,
I do not know of any other "different" squares. This Square Swapper event is the first one I have dropped in on.
Thank you so much for the invitation to the next time around but all jokes aside, I cannot even sew on a button. When one comes off a shirt, I take it to my alterations lady. I did give it a try but I stuck myself so many times ... and that button I put back on the shirt did not look like the others ...only the edges of the button were visible. It had a great big wad of tangled up thread in the middle of it. I think I went into overdrive in trying to do a good job and sewed it on too much.
And ... Arwen, I really do think it is a wonderful thing for so many people to have so much fun ... umm ... knitting squares.
