I like this product to make 1 1/4" finished half sq. triangles much better than the large sheets because you can use them with 5" precuts or your own 5" squares. They also make it possible to obtain a variety of color combos needed for reproduction quilts. The small size is easy to turn when sewing. Nice to use with your scraps as well. I can now make all those lovely quilts that use small 1/2 sq. triangles that previously felt to difficult to attempt.
