I have the customer buy the fabric, batting and thread. I estimate the number of hours it will take me. Then I work for $8.00 per hour and keep track of my time and deliver a time sheet to them showing what day I worked on it, the number of hours I worked and what was accomplished. Because they bought the fabric and stuff up front and agreed to an estimate of hours, they know what they are getting into. The detailed time sheet shows them I was not "padding" the bill and while I know that $8.00 per hour isn't a huge amount, it's sufficient for me. I'm retired with a good income and enjoy quilting. This way I get a small income for doing what I already enjoy.
