Naked Card Revolution
I've started packaging all cards in Glassine envelopes instead of Plastic Cellos to help the environment.
Glassine is a smooth and glossy paper, which is air, water and grease resistant. So still offers a little protection and cards look pretty cool inside.
At markets, I still have a few cards on display in Cello bags so you can see the full-colour card, any cards sold are handed over in a Glassine envelope
