I ran into the issue of having appliances that aren't magnetic so I wasn't able to attach our grocery lists anywhere. I made this simple holder that allows me to attach the magnetic grocery lists anywhere. It is designed to work with 9" x 3.5" grocery lists like the ones here: https://a.co/d/9jmgATt. 

Prints without supports

I used command strips to attach to the inside of a cabinet door.
