My heart hurts for you, This is a beautiful piece and how lucky he is to have you for a daughter, remembering him on Father's Day. He sounds like he has a lot of anger. Write your feelings down, don't send them, just do too vent, it helps. How about donating this to your local vets center,or library to honor the troops. This is a quilt of love.
You are very creative and I can't wait to see something else you have done,
