You may be wondering who has time to hand-paint a bunch of thumbtacks. I don't... but after seeing how awesome these look (and being a sucker for adding color and pattern everywhere I possibly can), I think I just might make time for this little project!
Grab some Sharpies, paint pens, nail polish, or even acrylic paints, then go crazy with patterns and colors! According to ModCloth, the trick to keeping your designs from simply flaking off the metal tacks is to use clear nail polish as a topcoat. Brilliant. Check out the ModCloth blog for more clever ideas!
