In-GENIE-ous triangle tool! Have you ever wished you could make triangles without measuring, without wasting fabric, without tearing away messy paper foundation, without cutting and aligning individual pieces, and without handling bias edges? Your wish just came true! TRIANGLE GENIE helps you do all this and more. And, the best part is GENIE does it from strips...the same strips for your squares and rectangles. For use with strips in five different sizes!
