no pattern -wanted large blocks so cut 9" centers then side frames are 2.5" and top/bottom are 2" and 3". That was more trouble than it was worth - wanted the block centers to be offset, but don't know that it's noticeable. 1" and 4" would have been better, maybe. Sashing is 2.5". Added borders at top and bottom just to make it long enough to tuck in. It's for a bunk so didn't want sides hanging down.
