Attached is a photo of an 17x23 quilt I made of 1 1/2" squares left over from a wedding quilt I made my older daughter, which is hanging in a bathroom where the shower is "never" used. The most important thing to remember is to have about an inch or so between the quilt and the wall so any moisture can easily evaporate so the quilt won't mildew. I am finishing another 16x20 quilt from the younger daughter's wedding quilt scraps, but that will have a sleeve on the back which will fit over the towel rack's dowel, which will have about 2" between wall and quilt.
