I quilt because I enjoy the process--- it is my hobby. If I give the result of my hobby, a quilt, to someone else, then I can't expect them to have the same level of enjoyment that I derived from quilting.
My MIL has painted porcelain objects for 40 years. She gives every one in our family Christmas ornaments, Easter eggs, and other painted objects every year. I have no guilt in saying a heart-felt thank you each time, without an obligation to display them all. I choose my favorites and pack the rest away, otherwise my house would be dominated by her paintings, which are not my taste.
She chooses to continue painting things even though she can see that I don't put all of them out. As long as DH doesn't ask me to display his mom's work, then I won't.
