Many quilters charge per square inch of the finished quilt. The cost includes factors such as the fabric used, the skill level required, the amount of time needed for the technique, the materials required, the quality of the batting and more. Many traditional quilters charge from 3 cents to 15 cents per square inch, says Katherine Bennett of Kat’s Out o’the Bag in Wilmington, North Carolina, with the price range reflecting the factors going into the quilt.
