This is a nice suggestion, and I've tried it, but my kitchen shelving is already a bit too cluttered as is.
I'm going to use it as a planter to create a gift for my MIL. She admired one of the plants I have in a pot, so I'm going to start one in the tin for her and give it to her as a gift. She loves interesting things, so I think this will make her very happy. And recently she has started to shift from heavy garden pots to lighter ones, so this will fit the bill perfectly. The second can (it comes in a 2 pack), I will make into a birdhouse for her (she has a birdhouse collection.) Or maybe, we can make the birdhouse together. That would be fun.
Thanks for all the ideas guys!
