How to paint a cow on a propane tank

Since you have no artistic ability, like me, you'll need a template or a homemade decal/sticker. For a template, you'd just print-out a picture of a cow and cut out its outline to paint onto the tank. For a decal/sticker, you'd cut-out the printed picture and simply paint the backside with polyurethane, apply it to the tank and then once dry paint over it with polyurethane.
