My dad passed away 3 years ago this October. He retired from the army with 21 years service. He served in WW 2, Korea and Vietnam. I've been in the process of gathering his medals etc. to make a flag display/shadow box. I'm fairly set on the design of the box, but I can't figure out how to attach the medals, patches and a photo or two to the inside. I plan on covering the inside with green felt. Any ideas how to attach this stuff to the inside?
