canvas bags *I got mine at Michaels they came in a pack of 3. Now the grown-ups have a bag, too. Sadly, my husband can tell you how grumpy I get, too.
cars & trucks with cool treads
paper to put in the bag to protect from bleeding paint
*Insider tip: take the cars for a painted test drive before you go for the real thing. Not all treads turn out as cool as you may think. Sometimes there is one part that sticks out father than the rest so you could just get a set of lines instead of tire tread.
3. Drive away....
