So sorry to hear about the loss of your Dad. My Dad passed away six years ago, it seems like yesterday, but now I can think about him laughing and smiling and not so much about the reasons that took him. We saved some of my dads favorite shirts and I am just now getting around to trying to figure out what kind of squares I want to make that can incorporate some of the fabric of his shirts. My sister made a quilt for my Mom and used some of the shirt fabic and it came out beautiful. You will find a way too to treasure your Dad's memories in special ways. It gets better and you will find that doing your favorite things will once again become a comfort for you.
