Do you think sharpie would do the trick or would I have to work with some fabric?
Personally, I'd use a heat-settable fabric marker rather than sharpie; less chance of it running (though I'd still test a little somewhere inconspicuous first). If your fabric has a fairly smooth surface, you could try fabric paint -- it generally looks cleaner than colouring over that size of an area. Paint if you can, marker if you can't and really don't want to try fabric; if you do graft or overlay fabric, get something with equivalent stretch.
(Dye isn't really a good option in that sort of situation, IMO. Just sayin', given the thread we're in. XD )
