I ask them what colors they want and then look for fabric in those colors. I give them a price range based on fabrics and size. If they want specific fabrics that will cost more I raise the price accordingly. I pick the pattern which is usually fairly simple and quick to assemble. The most expensive quilts I have made are a giant dahlia and my current project an oversize king out of 30's reproduction fabrics which you cannot find on sale. I have probably made over 20 quilts for others. You can never get enough money for labor but you are giving someone something you created and they cannot get elsewhere......
