I just got 2 patches from my sensei, one is the school badge, and the other is an organisation patch. I aint too sure if its compuslsory to have them on my Gi, if they are then I guess I will have to put them on, but my only problem is the Organisation one is big and ugly looking, so Im hoping I dont have too haha. The school one will look good when its on, but that organisation one....yeah....not so good!
