I have volunteered but never been asked. Although my DD cruises the quilt lab when she is home and points out anything she thinks is looking good and asks 'anybody got dibs on that one?' LOL That is the kind of 'giving quilt' you want to make!
Just like you said ' anything you make I will love'. That is the essence of a gift from the heart!
Once you start asking what they like in colors and prints, they may get the idea they are in charge of the design, and all the fun goes out of it. Maybe then you suggest you could get a nice comforter for half the price at Macy's! Or maybe an electric blanket?
