Paper Trey Ink. They are called Simple Seashells and come with coordinating dies. My card is for our Summer Themed CAS challenge over at The Outlawz. I love the multi-step stamping with this set. I then paired it with the Sand Swatch and Just for You Mini Sets also from Paper Trey Ink. Nothing says summer to me more than the beach!! Why don't you join us at The Outlawz and share your summery CAS cards.
