Fraying
I've recently made a quilt top in the 'Square dance' pattern. There are close to a million tiny pieces, and I'm very proud of it. Here's my problem: I've decided to make it into a duvet cover by sewing a sheet onto the back of it, like a very large pillow case. The pieces all have 1/4 inch seams, and I fear it would ravel in the wash. Is there a product that I could spray onto the back, or iron onto the back, that wouldn't make it too stiff yet would make it less likely to ravel? I would, of course launder it right side out.
The reason I wanted to turn it into a duvet cover was to avoid quilting it. The pinwheels are about 3 inches and the 4 arms of the pinwheels are about 1/2" x 1" and about 1 1/2 inches long. In order to make the pinwheels 'pop' I would have to quilt around the outside of each and every pinwheel, and that's more than I think I'm capable of. I thought that if I could 'glue' a sheet to the underside of the top I could avoid having to quilt it.
