Thank you to Claire at A Little Something in the Meantime, she told me about these boxes that can be found at Jysk, a Canadian store similar to Ikea. They are fairly inexpensive and very lightweight.
I stained them with Minwax’s special walnut, a little haphazardly as I didn’t want them to look too uniform.
I cut out black vinyl on my cricut and applied that rather than painting them in. As before, I don’t have a way to hang them but I’m working on an idea ;)
I hope you are enjoying your weekend!
