One item I use from time to time, in both research collections and in home gardening, is specimen tags. Paper or card stock tags are usually adequate but even in protected museum environments, ink fades and tags get wet. Years ago I saw metal tags on some museum specimens and decided I could easily make my own using soda cans or other embossing friendly scrap metal. It's possible to make very nice tags that look as good or better than you can buy or even just cut up a few soda cans for ease and utility. Aluminum will corrode if exposed to certain chemicals but for the most part you can use the same tags indefinitely from season to season or for long term storage.

The cans are easily cut with common craft or kitchen scissors and one hanger will make three or four "posts" to hang them from. The last can I cut up yielded about ten tags.
I need to make another batch soon and will post a how-to soon as I get a chance.
