I've actually done what true4uca is talking about.....don't sew your bindings together....bind each side separately......I did mine by leaving a tail of binding at the beginning of each side. The next side's beginning covers the raw edge ending of the previous side...... once i had the binding stitched on, i turned that tail under - making the "corner" before i started hand stitching the binding to the back. Hope this makes sense. So many things are easy to DO than to TELL !!!
