How To Make Half Square Triangles — Method Two

Last time I posted about making half square triangles, I showed you the traditional method, which yields two HST pieces.

This second method yields four HST pieces.

For this project, I used:

Cut two identical squares from different fabrics.

Stack the squares so that the right sides of the fabric are touching.

Sew the squares together on all four edges with a ¼” seam allowance.


Make two diagonal cuts through the center of your square.

Press each HST open and trim off dog ears.

What do I like about this method?

You can quickly produce a lot of HST very quickly and with fewer seams to sew.

What do I not like about this method?

You need to start with larger squares, that I usually don’t cut, in order to end up with reasonably sized HST and the math is a bit more complicated when trying to figure out exactly how big you should cut your original squares.

Disclaimer: I included affiliate links to all the tools I used for this project. They don’t make my sewing machine anymore, but the one I linked is a new and improved version!
