I machine bind all my quilts. I cannot physically sit and hand sew a great big quilt. Like others have said, I make the binding 3 inches and then fold in half. Attach to the back and pull to the front. Sometimes I just straight stitich in a thread to match the quilting thread so when it shows on the back it coordinates as wellas on the front.I have used straight stitches which sort of look like a frame on the back. I have also done the front with zig zag stitches. Some other decorative stitches look great too.
