The "White Librarian" -- plans
I really liked this design that redpepperquilts had for sale on etsy. ('Bricks and Stones' quilt pattern) I bought a copy, even though I knew it was for a lap-sized quilt, and I'd need to adapt it to get the bed-sized quilt I wanted. It's a really fun idea, though.
Some quick drafting in Illustrator later and I've got the general plan; I chose a 72" square quilt because 72 is a multiple of 4, 6, and 8.
Haven't started it yet; it's in the queue, though.
