Do you have a woodburner? If so, you could cut a circle from 1.5" orange ribbon by using a half-dollar (like here: http://hipgirlclips.com/forums/how-m...tructions.html
) and use a fine-point paint pen to draw on the lines. Either that or glue 1/8" ribbon or itty bitty ric rack for the lines.
I have the ideas all written down to make basketballs, baseballs, soccer balls, etc, but I haven't made any 'prototypes' yet. I just know it would work though!
