I charge the same prices you do and I also feehand. When I get a new customer, I measure the quilt in front of her, write it in the book, so she can see the charges and since I have a few quilts hanging around I show her what I do. If she is pleased with that, then we have a deal. Normally, I will tell the person, before they come, the measurement of the backing (four inches all around). I make a practice of never ever sewing anything on a quilt. If the backing is not big enough or they have missed seams on the quilt, they have to come and get it and fix it first. I have never had a complaint. Another thing, I will charge a minimum of 50.00 for a small quilt as it's not worth it for me to take out the machine and do all the set up for less....for instance 60x60 would be 36.00 dollars but I will charge 50.00.
