Half squares, triangles, squares, who knew geometry would be this much fun! The GO! Half Square-8" Finished Triangle die cleanly cuts through multiple fabric layers. Two half square triangles sewn together form a perfect 8" finished square. Design your own quilt or use with GO! Half Square-8 1/2" (55058) and GO! Quarter Square-8" Finished Triangle (55399) for quick and easy large-scale pieced quilts. View the GO! Mix and Match Quilt Block Collection Chart which shows how the GO! Hip to Be Square dies can be combined together and with existing GO! dies to create classic 6", 8", 9" or 12" 4-patch and 9-patch blocks.
