Built this herb planter box and used left over aluminum sheeting to line the inside.

It’s overkill for sure, but I had the sheeting laying around and I’m not too keen on lining the inside with plastic. Overall I’m very happy with it, planning on planting some oregano and basil this spring. I moved the chives in there which were coming up from last year in another pot. I’m not sure if I’ll apply a stain to it, maybe once it warms up I’ll use a simple linseed oil finish.
