My technique for this Thursday is "Ghosting". I stamped a word script stamp with Versamark onto some glossy paper and then rubbed some black ink over top. The ink resisted where the Versamark was stamped onto it for a ghostly look. Then I stamped Mike's spooky tree on top.
Alas this card also did not go through the card slot and extra postage was needed. Again I probably should have seen it coming but I honestly thought all the dimensionals I used to pop up the image would just squish flat. Oh well. I was still trying at this point.
