Take a deep breath. I make memory quilts all the time, for good and bad reasons and the 1st few blocks are the toughest. Look at it this way, the way they will "remember when dad wore that shirt to the baseball game, or remember he wore that in that photo we have with the goofy face he made....etc... Your doing a wonderful thing for them and everytime they curl up with that quilt the will have a hug from dad.
