I've read it several times on this board recently that the sizzix big shot and big shot pro are not made with quilters in mind. The sizzix site has an entire section called quilting that consists of lots of quilt related dies including strip cutting dies for both the big shot/big kick and the big shot pro.
all of these dies fit in the big kick and big shot (regular, not pro) and are quilter's dies
all of these dies fit in the big shot pro and are quilter's dies
You do have to have the extended cutting pads for the longer dies (unless you buy the westminster model which comes with them) but they ARE for quilters!!
