Karleen Daugherty (aka "Aunt Ice Cream") gave me her quilting scraps which I tore into 2 inch strips. I attached a second layer, using the rag rug method, by cutting a slit into the bottom of the first strip, pushing a second strip through, and then pulling the end of that second strip through another slit on the second strip's opposite end. Is that clear as mud?
I cannot claim the idea as my own. I saw something similar as a bed canopy at Anthropologie, one of my FAVORITE stores. I don't go to buy, but just to look at the new store displays which are so clever.
