I laid it out. At first, I was thinking "what have I done?" and I really didn't like it, but as I kept working, it all sort of came together and now I think it's going to be great!
I'm not sure if there's a trick to sewing it together so it'll stay square, but I'm just trying to be as consistent as possible. It'll have a narrow border, then a wider one, then the binding (although I may use the same fabric for the outer border and the binding).
Believe it or not, I took quite a while arranging and rearranging to make it look "artfully scrambled". I just came up with that phrase. You heard it here first. Artfully Scrambled.
