Our club is getting ready to host a competition and we'd like to cover the boards like they do at major competitions. I've heard it's expensive but think that hiding all the puck marks and otherwise shoddy looking boards will improve the competition. Can anyone tell me what material is used for this purpose? Any suggested sources of supply? Anything that would help us track it down would really be appreciated. So far, I've struck out with google but I really don't know what I'm looking for other than thin, opaque plastic of some sort.
