I tend not to make the same quilt twice. But my first 2 quilts were 9 patch w 2.5" squares. The first was all pieced by hand front and back, and quilted by hand, initially tied. The second one was alternated with 6.5" squares. The reason for 2 9 patches was an overabundance of 2.5" squares. Then I've remade quilts that were lost in a hurricane, but made them better. For baby quilts, I've added borders to enlarge a panel. I don't know if that qualifies as the same. My problem is that I like to do different things.
