The GO! Signature Block is designed to coordinate with the GO! Half Square – 3" Finished Triangle (55009) and the GO! Half Square – 1" Finished Triangle (55320). Sew two 3" finished half square triangles to the long sides to create a 4 1/2" finished square, or attach four 1" finished half square triangles to the short sides to form a 6 7/16" x 2 1/8" rectangle. This versatile shape is perfect for adding signatures to personalize a quilt or for creating signature blocks to be signed at showers, weddings, and other special celebrations.
