I love Pottery Barn. Let us make no mistake about this. LOVE. Pottery. Barn. However, when I saw these a few weeks ago and I was conflicted. These are a polyresin construction and you can get four for $16.
Now my DIYer mind has these as free for myself because I already own chalkboard paint and luckily some rocks. I am going to experiment and see if I can recreate the same look for less! Wish me luck!!
