They're ideal for painting with chalkboard paint!However, the wood is so thin that the moisture in the paint will make them warp. Don't worry! Once the paint is dry to the touch just gather your chalkboard tags and place them under something heavy for a few of hours to straighten them out again.They're the perfect size to hang on a doorknob as a reminder for a child to clean their room. Or a fun way to congratulate newly weds. How about as little something extra for a birthday. Or a little Thank You to someone special for her thoughtfulness. There are so many possibilities!
