When I sell quilts I triple the cost of fabric (including backing)at todays present price. If I bought it on sale earlier I still figure the price on todays going price. I then add in actual price of batting and machine quilting and any other embellishments. ( I send my quilts to a long armer). You will be amazed at what that adds up to and your friend may. change his/her mind and you'll be off the hook!
