The Trick of the Half-Square Triangles

Quilters spend a lot of doing repetitive tasks. And whenever I discover a way to reduce the time involved in any repetitive task, I am so there. There are several wonderful designs that start from the half-square triangle. And if you're asking what a half-square triangle is, then do this:

Draw a square. Then draw a line from one corner to its opposite. Shade one-half of the square. Poof! Half-square triangles. Now, here's the magic trick part (you can click on any of these photos to see the detail).

Cut two squares of different fabrics the same size (picture 1). It doesn't matter whether you start with 6" squares or 2" squares, as long as these 2 squares are the same size. Place right sides together. Draw a line from corner to corner with a pen or a pencil - that will eventually be your cutting line (picture 2). Using a 1/4" seam allowance, sew a seam on either side of your drawn diagonal line and press (picture 3). Cut on the line you originally drew (picture 4) and press open (last picture).

Presto! You now have 2 half-square triangles! Cut off the little tiny triangle parts that are sticking out - some quilters call these rabbit ears. Now you have a square that can be sewn to another square.

Isn't this a great trick?
