If not, just take your time on your home sewing machine. I don't believe that doing a stitch in the ditch will help you with the problem you are having with the shredding. It might just make it worse.

I had a fabric I was using in a quilt start raveling like crazy. It matched the other fabrics so well, that I was determined to use it. For every seam with that fabric, I sewed the 1/4" seam and then went back and sewed a wavy 1/8" average seam closer to the edge before ironing the block or sewing any other parts to it. My wavy seam stabilized the fabric. The quilt has been washed many times and is fine.
