Puzzle box pattern--set in seams?
Has anyone done Tracey Brookshier's Puzzle Box pattern? I thought it might be good for my sister, a new quilter, to use on some large-pattern fabric she bought...but looking at it online, I can't see how it's done unless there are set-in (Y) seams...and my sister is NOT going to go for that.
Anyone done this pattern? Are there set-in seams?
