I hope this doesn't sound unsentimental or anything but I was thinking that those caps would be a Godsend to cancer patients. Take a good picture of the collection and frame it. Donate the caps in memory of the loved one. I'm aware of the need because I sit in the waiting room of a cancer treatment center with my mom. I also remember teaching a child (first grade) who was undergoing chemo at the time. He loved wearing the caps that people gave to him. Just a thought.
