Pricing and design are things you should definitely discuss with the longarmer. Most, I think, charge by the square inch, and that charge is determined by how complicated the design is. Custom quilting (something other than an allover design) and dense quilting naturally cost more. There may also be a minimum charge, since it takes time to load the quilt. There may also be a charge for thread. Depending on what you want (and are willing to pay for), the cost of the longarming could vary tremendously, even on a small quilt.
