I am a relative newbie to the world or Grass Dancing. I danced for a while a few years ago but not since. I am looking to get back into it. I want to make new regalia and I have a few ideas going but I don't know what is appropriate or not. The biggest thing is that I am wondering if it is okay to put bead or quill work on my aprons. Aside from this I am curious as to wether or not there are any other specifc rules or regulations or just things that are frowned upon?
