I've found that a lot of times, I have to just make my own stuff i want, because I can't find it or its not available. I suggest purchasing this patch from ebay and putting it on any color blank hat you'd like. Should be easy to do and look pretty good. http://www.ebay.com/itm/UND-North-Dakota-Fighting-Sioux-Vintage-Embroidered-Iron-On-Patch-NOS-/111776228922
