Half-Square Triangles, 4 in. finished
Half-Square Triangles, 4 in. finished by Triangles on a Roll. This paper grid is a pattern for sewing and cutting, printed on a 50-foot long roll of paper that enables you to make as many or as few triangles as you need with two different fabrics (each roll makes hundreds of blocks). Simply select your fabrics, place them together, place the paper on top of the fabric, pin the layers together, sew on the dotted lines and cut on the solid lines. Seam allowances are built in. Instructions are provided on the paper. No more cutting individual squares, cutting and sewing on the bias or trimming each block -- achieve easy, precise results with Triangles on a Roll.
