I've typically seen glass etching on the bottom of casserole dishes and it just hasn't been my thing. But this is super- the instructions are simple and the results are too, which is exactly the way I like it. (I'm still dreaming about these jars/this cupboard though! Dear Jamie, please open a US shop.)
I found this DIY on the new & great looking blog dear Inspiration (friend Lindsey's cousin). You should bookmark it.
Happy Thanksgiving tomorrow!
