luvmy2bts~ I'd like to thank you for those links as well.
In the second link there are two different "ideal" sizes, one by Donna Poster, and one by Hargrave & Craig, I'd have to agree more with the later. Donna's idea that a full size quilt would be 106" just seems excessive. My bed, which I share, is a full size, and I love the quilts that are square around 86"x86" because it's hard to tell which way to put it on the bed, when one is only a couple of inches longer. We're not the tallest people in the world, but 106" is 20 MORE inches, and that's a lot of quilting! :D
What size are you hoping to work on?
