I am working on a queen-sized quilt, but I don't have a queen-sized design wall. Mine is actually portable, since it sits in front of the closet door in my small sewing room, and sometimes I need in that closet.
But to enlarge it so that more of the blocks on this Labyrinth Walk quilt fit, I have turned it sideways and set it on upside down buckets and Kleenex boxes. It looks pretty primitive, but I believe it will get the job done. My last three large sections will have to dangle from the bottom, and I don't think borders will fit on it, but at least I have made it sort of larger.
See...I am feeling rather clever.

Now, if I can finish this next block. I haven't quite wrapped my brain around it yet and I needed motivation to continue. My enlarged design wall has given me that motivation.
