Hi Dingle and welcome.
I don't know if anyone has suggested this but I have done it a few times and it always turns out great. Make a pieced binding with the fabric you have left. I had 12x2.5 strips left over and sewed these strips together on the diagonal, pressed the seams to one side, folded it in half lengthwise, sewed it to the front of my quilt then turned it to the back and hand stitched it down. Turned out wonderful and I didn't have to go out and buy more fabric. Good luck with whatever you choose to do.
