I decided to try something different with Jonathan. I went to Texas Art Supply and purchased stretcher bars one inch bigger than the finished rug. I put the stretcher bars together and stretched black duck twill canvas over the frame, stapling it to the back. Then I sewed the rug onto the duck, stretching it tight to the edge as I sewed the binding to the duck fabric.
I love it because it is stretched tight and flat and looks just like a painting hanging in my living room.
