For these cards I started by stamping a Tim Holtz stamp with white acrylic paint. After it dried, I buffed in a few hues of Distress Inks. The key to this technique is wiping down the paint after you have inked. Once I did this, the white resist really showed through. I added a few old used postage stamps, air mail stickers, rub ons as well as another stamped image of pen nibs. The edges were sanded and inked to frame out the cards. I forgot how much fun ATC's can be. They are so small and quick!
Another new item I tried was Lisa Pavelka's Magic Glos. It was really easy and fun. This resin like material cures in the sunlight or under a UV light. I had issues with air bubbles, but I really don't mind how they look. I used some small bits of wonderful paper I picked up at an amazing store in Ann Arbor called Hollanders for the background and layered in bits of watch parts.
