Create the illusion of 3-D with color, value, and contrast. Using the new Stripometric ruler, we'll cut and build columns of measured strips with 60 degree cut ends. This new updated cutting and constructing method eliminates the need to sew a long series of identical triangles. We'll create the perfect project for your math-loving, mechanical, or engineering gift recipient and spend much less time doing it. www.quiltersclinic.com
