"ghost deck" playing cards (monotone)

Hello, While I was trying to design a regular deck of playing cards, I stumbled on a neat effect. I'm not sure if there's a practical purpose for it, but I thought it was cool enough to make a whole deck. The intent was to make playing cards that you couldn't see through when held up to a light, the result were cards that the image disappeared when held up to a light. It only works for me with the filament I have listed (it's all I had), other colors seemed to show through so I made them all monotone grey. The face cards are handed (left and right) to help keep them sorted (jokers tagged by ghost boy). Each card is 5 layers thick, (3 white and 2 multi-color). Each layer is only .08 thick, so don't forget to level (and clean!) your bed (I used a cool plate, you can still see some of the spiraling that way). Note: this works for me with the filament specified, your results may vary.
