I made one many years ago. It hangs in my office and is getting a bit faded. I don't remember it being terribly difficult but does require precise sewing to get it all to match up. I may make another at some point. I love FLW's designs, especially his windows. And since I was born in Buffalo, my quilt is from one of the houses he designed in Buffalo, along with buying all the fabric there while visiting. Reminds me of my roots and family.
