Sorry that my explanation wasn't clear. Unfortunately I can't find a picture of the Twister tool - it is a square piece of acrylic with what appears to be lines that are angled. When you make a twister quilt you first sew together the fabric squares - then using the twister tool cut the fabric apart by placing the tool on the seams and cutting out the squares. The tool has little balls at each corner so the tool sits flat and doesn't rock when you cut. You can see a tutorial on it at the MSQC - The Amazing Twister Tool – Quilting Made Easy.
