These dies are just the right size for cardmaking and scrapbooking. The Mini Butterfly set will be the perfect addition to spring, summer or feminine projects. These dies are part of Sizzix's Movers & Shapers line. This line gives crafters so many more creative options. The dies are magnetic, allowing crafters to position the die exactly where they want it on a card or envelope to create a window. Just put the die into any of the Movers & Shapers base dies or base trays and run them through a BIGKick, Big Shot or Vagabond machine (with a pair of appropriately-sized Cutting Pads), all sold separately. This die was created by Tim Holtz and features his trademark cutting-edge designs. When cut, the butterflies measure 1 7/8" x 1 1/8" to 2" x 1", approximately.
