Hi, I've done a quick look around but couldn't find the topic.
My cheap (but ever so comfortable) pair of gi trousers is wearing out at the knees. The reinforcement threads that form an 'x' on the knees have mostly gone and that's fine but one of the knees has what seems to be the start to a nice airing vent. The threads are still running across this small hole so it's not too bad..yet.
So how do people usually patch their gi trousers? Do you put a patch of white cloth on the inside? outside? or both? Or is there a fancier way of doing it? Tips on keeping the trousers intact after intense suwari-waza classes are also appreciated.
