You should be proud. You know that he is. What a great way to pay tribute to your father.
I would pass on the connection to your dad to the people who receive your quilts. Every one of the people that I have met who received a quilt from QOV always ask what motivated/inspired the quilt and my participation. If they have been given, drop them a note to mention your dad. I know that they would appreciate knowing that part of your story.
