Empty tins: I just wiped them out. I didn't bother pulling the labels off or anything like that.

Measured and cut strips of paper and used a heavy duty double stick tape rather than glue. And by heavy duty I mean heavy duty. It's industrial strength double stick tape that they use to put together displays at Home Depot.

I removed a few pictures from my magnetic strip and artfully arranged my tins, screwing them into the wall with a single screw through the center.
Viola! Filled with various supplies that were just sitting in empty boxes and bags. I did save the lids and I'm sure I'll find a use for them at some point.
Of course, you can't really see the sides of the tins unless sitting at my computer, but I couldn't just leave them uncovered.

I've been told that if I keep up my current rate of tea drinking I'll have enough tins to fill the entire wall! (There are currently 4 waiting to be opened in my kitchen!)
