Im not sure what you mean.

Maybe this will clear it up-
On my jersey, my sleeves have a patch of velcro on it (velcro square to attach things). To make the otherside not look plain (right arm), since ive got some other patches on the left arm, I was just going to put this there. Im still thinking whether to just draw in another arm on the image or put something else, im trying but I really suck at drawing so I cant get it to look decent...thats also why im not doing a front view lol would look terrible.
