I posted a 12x12 mini quilt a couple of weeks ago that I am using on the front door window to keep the morning sun out of my eye. I was afraid that hanging the square on point the side corners might curl in, so in the binding I sewed very narrow strips of plastic cut from a dish soap bottle. The strips are on the back side of the quilt but totally hidden in the binding. It gives the quilt just enough body to stay flat. The plastic strip is not as long as the side of the quilt. This does not answer your question about the quilt show but keeps the side points where they belong. BTW cool wall hanging.
