Last year I made 19 quilts, lap and kid sized. To enable me to make that many I started sewing the binding on by machine. I sew down on back bring to front and sew from corner to corner, cut the thread and start after making the miter and backstitch a couple tomes then sew to next corner and finish like that. It is much faster than hand sewing and much less likely to come out. Warm quilts are more important than hand sewn binding.
