I understand this problem. I gave my son and DIL a scrappy quilt my mother (now deceased) and I had lovingly made. A few years later I was visiting their home and noticed the quilt was on the floor of their bedroom as a dog bed for their two dogs. I had a quiet, private chat with my son about the sentimental value, time, love etc. that went into the quilt and how to take care of it. I suggested they keep it on a bed or in a cupboard so my grandson could appreciate it one day. I have not seen the quilt on the floor so I am assuming and hoping it is in a cupboard. You don't want them to feel guilty or obligated about the quilt but you just want them to appreciate and value it on all levels.
