It depends on so many things...what part of the country you are in, what type of pattern you choose (panto, custom, semi-custom), how many thread changes, pattern density, whether other services are included (binding, batting, backing, etc), too many variables to give an "average" price. Pricing here starts with a price per square inch for complexity of pattern and then all those other things factor in. I, too, think it's worth it for large quilts.
