Today I roamed the aisles at Home Depot a bit looking for something somewhat cute to attach to this handout with a construction theme. I ended up getting carpenter pencils for $0.19 each. If you don't know what I'm talking about they can usually be found at the cashier table & here's a photo:

I also considered nail polish since we use "nails" in construction or just getting a large screw, washer & bolt to tie to the handout.
