Start with the cost of the quilting. Add $100 for fabric & thread. Add another $100 for your labor. Total and add another 20% of that. Now stand back and consider if you have priced your labor and fabric too low. Have another go at it. People mostly buy because they can't make it themselves. You are selling your talent. I would start with a higher price, and then come down if it looks like they're priced too high. With this information, you can put a ''sale'' tag on top of the original price tag. How 'bout this formula?
