My DS and a friend zooming around on a Pee Wee 50 and an Oset (kids electric trials bike), racing each other around the house and shed.
Used some really old Basic Grey paper, masked with black gesso, then decided it was too stark, so I whitewashed it and added extra white paint, stamped edges. Large cog is a chippie; most of the other embellies are unwanted gaskets from our local mower shop. Made arrow tag from paper offcut; made resin cogs from home made mold and painted them. Also used punchinella scored from a recycle shop.
