I'm going to be a monk for our local festival, my character is a monk I have a robe and cowl, the belt that came with it is fabric. I want to make a rope belt what size should a person use for a correct one.
I don't know if there is an "official" size for rope belts. but something I've seen commonly is about a 1/2 inch diameter cord
1/2" to an 1" is what I have used in the past.
I have also taken cotton clothesline and braided it. that worked pretty well.
