The Technique Lover's Challenge at SCS this week was hidden sentiments. You simply attach the main image by a brad, so it swings up to reveal the hidden sentiment underneath. How easy is that? This week's Card Positioning System (CPS219) sketch worked perfectly for me to try the technique.
Details: Stamps by Impression Obsession; paper by Cosmos Cricket; Inks are SU Kiwi Kiss and Stampcraft Baby Pink. Other supplies: mini brad, nesties, piercing tools.
