Use the Scallop Lace Envelope Bigz Die from Sizzix to make an elegant envelope from most thick materials (including paper, chipboard, cardstock, foam, magnet, fabric, leather, metallic foil, and more). Bigz dies are intended only for use with the BIGkick, Big Shot and Vagabond machines. They require a Cutting Pad and a Premium Crease Pad (all sold separately). The die itself is 5 1/2" x 6" and designed by Scrappy Cat. The assembled envelope is approximately 2 1/4" x 1 7/8".
