Be thankful. Most people do not want to pay for your time, just the materials. I have to say, he was thankful that you made a beautiful quilt and he wanted to thank you in his way. He does not quilt, and he know your talents show that you love to quilt. When I make a quilt for someone, I give an estiment, and when they pick up the quilt, some of them make me feel like I am short changing them. I usually take the cost of the materials and double for the cost of my time. Put the extra aside and when someone shorts your time, remember your very thankful customer.
