This was one of the vintage sheet FQ's I received in my swap box last week. I was instantly drawn to this particular piece and decided to turn it into a pillow for my living room couch.
I just sandwiched the FQ, did simple meandering quilting on it, cut it down to size, and sewed it to the backing.
For the back of the pillow I used a men's dress shirt. The buttons make for easy removal of the cover whenever it needs a wash. I probably could've made the cover a teensy bit bigger as the buttons pull a bit, but I'm not fixing it.
