The Decorative Border & Heart Sizzix Thinlits Die Set has an intricately-detailed design which will look elegant on any project. Jen Long-Philipsen designed this two-die set. Very thin and made in a process called chemical etching, these materials can cut through a single sheet of paper, cardstock, vellum or metallic foil with ease. These Thinlits dies are designed to be used in a BIGkick, Big Shot or Vagabond machine, along with Cutting Pads and the machine's Platform. (Using the Essentials Platform or Solo Platform and Shim will require you to also use an Extended Adapter or Solo Adapter.) Since these dies are so intricate, they may require as many as three passes through the machine to fully cut. If the shape is not separating from the die, try using the included ejection foam. The dies in this set measure 1 3/4" x 1 5/8" and 6 3/8" x 3". Also included in this package is a storage envelope to hold these dies. Cut off the front flap of this package and add it to the envelope to make it easy to identify. Each item is sold separately.
