I was wondering, if you wanted to put a patch on your gi, would you ask your instructor first before doing so? For example, say I wanted to put a small okinawan symbol on the left or right side of my chest or on the shoulder of my sleeve, should I just do it or ask for permisson? Just wondering what everyones thoughts were. Follow up question: if someone came into a dojo with patches from a previous style, do you think they should remove them?
