Iknow just how you feel, my granddaughter's mother is the same way, no matter what you give her she doesn't smile or get excited, sometimes doesn't even say thanks. I knitted up washcloths and socks for Christmas and she never acknowledge the gift. Later on said thank you for the Kohl's gift card, but never about the hand made gifts.
Personally I love the quilt and agree with yourstrulyquilts, so nice and homey feeling, old fashioned warmth. You can certainly feel good about what you made and the great work you did on it!! If she ever wants to give it back I would be more than happy and excited to take it off your hands, it's a work of love!!
