Root cover made of an old sock

For my windowarm project at school, I wanted to avoid spray painting the plastic bottles. But sewing some covers wasn’t an alternative option, my students having motor skill deficiencies.
An old black sock that I was about to throw away did the trick. I cut it in two, removing the heel part, and put both remaining parts one over the other to make the room darker for the roots.

Yeah I thought about the same thing with my some of my more desperately hole ridden socks
You may need two of them to block the light completely.
What about using aluminium foil?
@ Wai Kay : Hi ! It thinks it would work fine on the outside, but if light can enter on the inside, it could be reflected on the aluminum surface and maybe it wouldn’t be dark enough.
By the way, I did put two layers by folding the sock and it worked fine.
