How to Quilt Half Square Triangles

What is a HST or also known as a Half Square Triangle?

It’s a square made up of 2 facing triangles.

How to Make a Half Square Triangle Quilting Technique

There are various ways to make a half square triangle quilt block or entire quilt.

Method A: halfsquare_trianglequilts1

You could cut a whole lot of triangles which are ready to sew together into pairs.

Method B:

Or, depending on how many HST’s you need, you could take a lovely little short cut and do the following:

· Cut two squares of fabric (for our example make it two different fabrics). Each square needs to be 1” (2.5 cm) bigger than the finished HST unit. (cut 2 at 4,5” – 11,5 cm)

See image.


· Draw a diagonal line with a washable pen or invisible ink pen or even a soft pencil on the wrong side of one of the squares.

halfsquare_trianglequilts3· Now draw another line alongside that line with a ¼” (6 mm) apart. Draw another on the other side of the line as well. You will have 3 lines drawn on your fabric.

4· NOTE: the middle line is only a guide. Do not sew on this line.

· Place the squares on top of each other, with wrong sides outwards and your line drawing facing you.

· Now we sew a seam onto the outside lines.

· Trim your HST units down to be 3.5” (9 cm). Make sure that they are square by aligning the diagonals with the ruler diagonal. I have a special small square 4,5” ruler for this job – make life a whole lot easier. Find the 3,5”mark and make sure there is a little fabric on each side that can be cut off. Trim the two sides.

halfsquare_trianglequilts7· Turn your HST around and line up the diagonal to the ruler again – this time with the cut sides on the 3,5”line. Trim the other two sides.

halfsquare_trianglequilts8· You now have 2 HST units that measure 3,5” (9 cm).

Your First Half Square Triangle


That’s it for today.

Once you have made these and are comfortable with HST’s we will make a lovely quilt wall hanging (18” – 40cm) using this HST technique.

‘Till the next time,
