i charge $20 to do a binding...i only do the bindings for a couple customers who have arthritis and are just unable, but they also, love to quilt but are on fixed incomes...i do not mind doing the binds so i simply charge them $20. when i was first called and asked about doing the bindings my first lady told me she called the lady who was long-arm quilting her quilt and asked what she would charge to put the binding on (she makes the binding, i machine stitch it to one side, fold over and hand stitch) the quilter told her $150 .... it was a twin size quilt... so obviously binding is not something that quilter likes to do...i was stunned to hear that price and told the customer i would do it for $20...did not matter if someone else did the quilting...so i have stuck with that $20 what ever the size...hand quilting around here there are ladies charging 2 1/2 cents a square inch (measure length x width for the # of square inches)
