Love that quilt and your Dad will too. Like others said Go ahead and give it to him now! Let him enjoy it for that much longer! Dementis is such a sad thing to see them go through. I know since our SIL had it and he was just young. Only 40 when we lost him. I took care of him for awhile until it got to be to much for me since I had their baby to look after too. Finally had to put him in a nursing home. So I know what your going through. You will feel better by letting him enjoy the beauty of that quilt now. Prayers go up for you and your family and your DAD.
