The beginning of my Ink Collection Project

I've recently started a project that will (I hope) end with my ink samples and bottles being organized and typified. I'm using the Mnemosyne Word Cards that you might have seen on some other blogs. They're small and they're thick enough to keep ink from soaking through the cards but resilient enough that they show off the colors of the ink that I'm smearing on them. The only problem is that there are only 100 cards on a ring. I may need more.
