Piece a quilt with perfect 9" squares by using the Sizzix 9" Finished Square Bigz Pro Quilting Die. Bigz Pro dies are the largest dies Sizzix makes, measuring 12" x 12 3/4". The die-cut squares measure 9 1/2" unfinished, which will measure 9" when finished. This die can only be used in the Big Shot Pro machine, along with a Big Shot Pro Cutting Pad and a Big Shot Pro Crease Pad. The die will cut many materials, including fabric, paper, cardstock, chipboard, foam, metallic foil, magnet, leather, and much more. In order to get the best results with striped fabric or paper, line up the material with the cut blades rather than the edge of the die.
