Personally I would rather get a phone call than a thank you card, but no matter how they do it, everyone should thank a person for their thoughtfulness. My dh & I have 4 kids & 8 grandkids. We used to send money to all the grandies but now only send to the youngest 6 as they all are great about saying thank you. We had started sending cards only to the 2 oldest since they would never even acknowledge receiving the money, but now I just wish them a happy birthday on Facebook. A few months ago I gave quilted wallhangings to my 2 sisters and 2 nieces. One niece was not there, but after her mom gave her the wallhanging she sent me the nicest thank you note along with a picture of the wallhanging on the wall in her newly remodeled family room. That made me feel so good. My other niece gave me a big hug when she got her wallhanging. That makes it all worthwhile. I learned yrs ago not to give a large quilt to anyone unless I knew for a fact that they realized how much time and money goes in to making a handmade quilt because they just don't appreciate it and will more than likely compare it to the slave made ones you see at Wal-Mart!
