Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Super! (And those little tins hold 4 oz each, which is a lot of uses for most spices) The things I'd wonder about are:
1) Do the tins seal tightly enough to keep the spices fresh?
2) Will it be a constant bother to keep all the tins aligned and looking okay? (hey, if an unaligned receptacle bothers you . . .) To fix that, I'd put some small horizontal strips/pipes/molding/something to put the tins between so they are "registered" in horizontal rows, then just snug them up together in each row. Maybe 1/2" bright copper pipe with endcaps, either clearcoated or left to gain a patina.
I like the idea of the copper. They wouldn't have to be very wide, just a thin tube or strip (2.5mm or 5mm). Just a little something for the magnets to snug up to. As far as the tins, I have some similar but round ones that DW got when she worked at Teavana. The tops fit tightly, but are pretty easy to open.
