Since I got these large 1/2 gallon jars,
I slanted the crates at an angle.
This project was made with a screwdriver only
(back then I had the store cut the wood in half for me).
Anyway, I am still keeping the bottom crate to store potatoes.
(I use a placemat to keep the potatoes in the dark)
The top 2 crates now hold most of my glass jars.
I did not labeled my jars,
but you could paint the lids with chalkboard paint,
If you are looking into making a simple and cheap shelf to organize your kitchen,
this is definitely the way to go.
