I give them a hug when I mail them off and just hope they get there. One time, I gifted a baby quilt to a relative who was having a baby years ago. Didn't know them well, but they were relatives. They soon after moved far away. Met up at a family funeral years later. The wife searched me out to tell me how much the quilt meant to them, and thank-you again. So, what we think are gifts and presents, others often think of as treasures and ways of remembering us. Not a bad outcome for a hobby........
