Hi Quilty Friends!
Probably the most debatable streamlined piecing technique is the 4 At a Time Half-Square Triangles. Using the 4 At a Time method you are sewing on the bias of the fabric and not with the grain, which causes stretching with pressing.
The one thing that I find helps me be successful is using a starch product.
To follow along with the tutorial, you will need standard sewing supplies, (2) squares of fabric that are the same size (I am using 10" squares), a marking tool, a ruler and rotary cutter.
