Make your own pop-up cards with the Sizzix 3D Pop-Up Circle and Ribbon Platform Bigz Die. You will need extra-strong bond double-sided tape and a card base to create your pop-up card. The card size can be no smaller than A2 (4 1/4" x 5 1/2"). Personalize your card by adding any embellishments on the pop-up piece that you wish, and then use the die-cut ribbons from this die to embellish the card. This die measures 5 1/2" x 6" and was designed by Karen Burniston. Bigz dies can cut through many thick materials, including chipboard, fabric, cardstock, metallic foil, leather, foam, magnet and much more. Bigz dies are meant to be used with the BIGkick, Vagabond, and Big Shot machines along with one Cutting Pad and one Crease Pad. All additional items are sold separately. The measurement of the assembled die-cut shape is 3 1/4" x 3".
