This is the card we made (by request) last night at Stamp Club. It is totally cased from my friend Angie, whom I met at Convention! Thanks, Angie! You can't see it in the photo, but the trees are all glittery!
There are actually two techniques: shadow stamping and moonlighting. We first stamped the image from Lovely As a Tree in Night of Navy Craft ink, then applied Iridescent Ice EP and heated. Then we re-stamped the image (without re-inking) slightly offset, to give the shadow. Our mask is made from the 1 3/4" circle punch, and we applied it where we wanted our "moon." Then we added Navy Classic ink with a stampin sponge. We layered onto Basic Gray cardstock, added a ribbon to the card base, and popped up the focal image with dimensionals.
