I listed the "I Cube NY" postcards in my etsy shop this morning:
I have ~25 left, let me know if you would like a larger quantity than what is listed. I'm so glad I took the time to make these, they got a lot of love at the show. I did try burning the edges to give it a more authentic look, but this paper doesn't singe well. Live and learn.
I do still have the screens...hmm...what else can I make with the cube?
