Attic Window — 2 template set used for cutting the attic window blocks as shown in the finished quilt picture (Blocks or quilt NOT included). These templates have been sized to be used with the exact 1/4″ seam. You don’t need to guess as to what a “scant” quarter inch might mean. If you sew using these templates with a true 1/4″ seam your attic window will be perfectly flat upon completion. The seam allowance is included to allow you to cut multiple fabric layers both quickly and accurately. These templates have been quilter tested !! With the acrylic templates you get precision cutting for each block, or layers of blocks that you cut. These templates will last a lifetime, and will not wear down with continued use as with templates made of the template plastic.
