Maybe I am a bit forward, but it is always nice to call someone back and let them know you got the "thank you" card. Then proceed to tell them how much time you put into creating this quilt. Then tell them it was nice of their daughter (?) to pay for the extra fabric when she told you that she wanted a queen size. So without, getting into the situation of the commissioning part, they will know that it was your heart intention and personal gift. Albeit, my heart goes out to you.
