I do custom hand quilting to support my quilting habit. It is not something that you can even expect to even get minimum wage on. I keep track of the yards of thread used and charge about .70/yd. (More for quilts that "stick" hard and take more time to quilt.) I love to hand quilt! Have room in my house to have one in a big floor frame where I can just relax with some quilt time without having to get it out and put it away. If I am quilting for someone else, I am not spending money on my own quilts. (I don't need any more!) It is a great stress reliever for me and pays instead of me paying a therapist! (I charge extra for marking, binding, and any supplies that I purchase.) Not sure that answers your question. You have to decide what it is personally worth for you to do it and see if your customer agrees. If not, move on to other projects.
