You'll be singing a sweet tune when you're creating with the Patchwork Bird Bigz Die designed by Tim Holtz for Sizzix! There is one Bigz die included in the package that measures 5 1/2" x 6" x 5/8". The die cleanly cuts thick materials, including cardstock, chipboard, fabric, foam, magnet, leather, metallic foil, paper, and sandpaper (in limited use). Its wider size offers you more design options. Designed for use only with the BIGkick, Big Shot, and Vagabond machines and requires the use of a pair of Cutting Pads (all sold separately).
