Not only are these chalkboard tags adorable, but they are also extremely functional as well! They are perfect for those containers that you want to label, without having to commit to a certain phrase.
Regular classroom/sidewalk chalk works great (I've found that I like to dampen the tips of that chalk before I use it). But, I've also found an even better solution: Chalk Ink Markers!
Seriously love them!
(I found mine at my local craft store--but they can also be purchased on line)
