Thank you very much for this information. I think it solves a problem that I encounter with an unfinished quilt top that one of my friend gave me "to do what ever I wanted with it"
it was so badly sewned with unequal seam allowances etc... I undid it all to find out that the diamond shape were uneven. My only experience was with the Lemoyne star.. Because of your pictures now I know. I still have a zillion pieces to sew . thanks a million!
