One of the first blocks you learn how to make is the half square triangle or HST, and usually, it is used in conjunction with other pieces to create a more elaborate block.
But did you know there are entire quilt patterns that only call for HST blocks?
In this post, I’m going to show you some simple half-square triangle quilt patterns, a few free half-square triangle quilt patterns along with some paid patterns, and some more complex patterns that will use HST blocks to create a quilt top.
What Is a Half Square Triangle Quilt?
A half-square triangle is a foundational block that every quilter should know how to make. It is a square block that’s divided in half by two triangles.
You can follow these simple steps to create your own half-square triangle blocks:
- Take two squares of the same size (for example, two 5″ squares) and place them right sides together.
- Draw or mark a line from the top left corner down to the bottom right. This line will be your guide.
- Stitch a straight line ¼” away on either side of the guideline.
- Cut through both layers of fabric right on the guideline.
- Press your seam either to the left or right (usually towards the darker fabric). Now you have two HST blocks.
Now you may ask, “What do you do with half-square triangles?” There are so many different ways to use these blocks to create HST quilts.
You can make a quilt top entirely out of HST blocks, or you can use the HST blocks in a wide variety of different blocks and patterns. You will see what I mean in the example quilts I’ve curated for this post.
