Designed by Chris Stiasny, the finished quilt measures 82" square, and with the paper pieced foundations, each star will have the crisp points we all desire. The 12" Add-a-Quarter ruler is recommended - The specially designed lip on this ruler automatically allows 1/4 inch seam allowance to any angle for your rotary cutter. This is a great tool for paper piecing, and is also available for purchase.
