I Have been thinking about doing it to a deck or two for a week or so. I don't want to damage them, so I didn't even try, but I keep starting at the block of wax and thinking about it.
I haven't really done anything to the edges of any yet (same reason, don't want to mess them up), but I kinda want to throw some black or grey on one deck in particular. If I do and I wax em I will let you know how it turns out.
After I asked, I realized it might make the cards stick together.
