These were so easy and I think they would be great on a gift or attached to just about anything (jar of notions?).
Start with thin wood tags from the craft store. My came in a package of 8. Spray paint with chalkboard paint on both sides. Let dry. Using a white gel pen (made to show up on dark backgrounds) draw simple designs. Use a heat gun to immediately see the design cure. Don't hold the heat gun on it too long or it will turn the white to a silver. Wait until the designs are set and won't smear, then prime the tags with chalk. Wipe off and you are good to go!
