any graphic designers/illustrators out there?

I'm trying to create an image of the little green bubble that appears when you type a text on an iphone. I want to put the letters "tfti" in the bubble and then put it on a t-shirt.

this is just for fun and I'm only making one (inside joke with some friends) so if anyone feels like helping out a fellow Horn it would be much appreciated!

Thanks,
SAH
