Making Half-Square Triangle Units
For ease in construction, and to save myself time, I use triangle paper when making these
units. I love TRIANGLES ON A ROLL! You may have a favorite brand that you use.
For this project use triangle paper that makes 2” finished units.
To make HSTs "from scratch" try this method. It makes eight
2" finished half-square triangles at a time.
Accuracy is important. If you don’t have a 1/4" foot for your sewing machine, you might try
using a Quick Quarter tool with this method. It’s an inexpensive item, and easy to use.
Ask for it at your quilt shop.

- Cut a 6” square of red and a 6” square of light background
fabric. - On the wrong side of the light fabric draw diagonal lines from
corner to corner forming an X, as illustrated. - Place the right sides of the red and the light squares face to
face. - Sew a line of stitches one quarter inch away on both sides of
the drawn lines. - Follow the diagram and cut into 3” squares.
- Cut the squares diagonally on the drawn line, between the
rows of stitches. - Open each into a half-square triangle unit and press the seam toward the dark side.
With your square ruler carefully trim each unit to measure 2 ½” square.
