These are pinewood derby cars made out of moulding. I went to Home Depot, and bought a 7 foot long piece of moulding for about $4. I cut it into sections (I got about 75 cars out of the 7 foot long section), and spray painted the sections.
At Walmart, I bought two different sizes of thumbtacks (one in the office section, and one in the fabric section), but they were silver, so I spray painted them black.
