Use the 8 Inch Finished Square Bigz Pro die from Sizzix to cut fabric or hundreds of other materials. Die measures 12" x 12 3/4" and must be used with the Big Shot Pro Machine. Requires a Big Shot Pro Cutting Pad and a Big Shot Pro Crease Pad (each sold separately). Die cut size is 8" x 8" when finished and 8 1/2" x 8 1/2" when unfinished. Note: Die design may be angled. In order to get the best results when cutting on striped fabric, position the material so it lines up with the cut blades (and not the edge of the die).
