Ribbon Weave block

The Ribbon Weave block is made up of half square triangles, tri square triangles, and squares. It fits a 2 by 2 square grid layout and the finished block measures 8 inches square. I modified a block called Noon Light many years ago which may or may not make this block of my own creation. :) It certainly is my own name for this block. While every effort is made to be sure of accuracy, I am unable to test every variation. Before you cut up large amounts of fabric, cut and sew a test block or two. If you find any errors, please email me at "jeanne@myquiltgenie.com".
