I just thought that I would add a little not about the Half Square Triangles. I guess I really never read the instructions on how to make the HST or just thought that every one knows how to do these.... Well I am deeply sorry for those who do not - I was there in June and have now become a master at this....
Cutting your fabric:
Method 1
Light 3 ½” x 7” rectangle, cut 2 squares – 3 3/8” x 3 3/8”.
From the medium/dark 3 ½” x 7” rectangle, cut 2 squares – 3 3/8” x 3 3/8”.
Cut each square once on the diagonal to make two triangles.
With right sides together, match on light triangle to on medium/dark triangle.
Sew a scant ¼” seam allowance on the long edge of the triangles.
Press seam toward the medium/dark fabric
Method 2
Light 3½”x 7” rectangle and on medium/dark 3 ½” x 7” rectangle in half to make four squares measuring 3 ½” x 3 ½”. Mark a diagonal line on the wrong side of the light square from one corner to the opposing corner. Align a light square to a medium/dark square with the right sides together. Sew a scant ¼” seam allowance on both sides of the drawn line. Cut apart on the drawn line and press the seams toward the medium/dark fabric. Using a small square ruler, trim the half-triangle square to measure 3” x 3”
I have done both and methods and 2 works best for me.
I hope that this helps.
I have a few additions to add to this, I hope this will help
