Sorry, I have no experience with the type of emblem you are describing. I made an Army quilt for my son as a gift when he completed basic training and used an Army emblem panel as the center of the quilt. I purchased the emblem panel at Wal Mart. This was several years ago, but I still see military emblem panels, other than just Army, and sometimes coordinating fabric at WalMart even now.
Sorry no help with your question, good luck with your quilt!
