The Sunflower/Poinsettia Petals Bigz Die is from the Quilting by Design Collection by Sizzix. The die cuts cleanly through fabric and many types of thick materials. It is for use with the Vagabond, BIGkick, and Big Shot machines only, and requires a pair of Cutting Pads. (All items are sold separately.) The die measures 5 1/2" x 6", and the petals measure 1/2" x 1 1/4" to 1 3/4" x 4".
