What Is A Pinwheel Quilt Block?

Before we make one we should probably know what one is right? The pinwheel block is simply four half-square triangles put together. That makes them a pre-cut fabric-friendly quilt pattern and if you use pre-cut fabric it will make the blocks come together even quicker. It’s one of my favorite quilt blocks!

How Do I Make A Pinwheel Quilt Block?

As I said before a pinwheel block is just four half-square triangles so our first step is to make them. The method of making half-square triangles is up to you, you can make them two at a time, don’t forget to check out our tutorial on making them without drawing a line. You can also do them eight at a time too! If you opt to make your half-square triangles two at a time you will need 2 sets for each pinwheel block and if you make them eight at a time you’ll get two pinwheel blocks. You can also use an Accuquilt die to cut your half square triangles.

What size will my quilt block be?

Your block size will depend on how big you make your half-square triangles. Typically you add 7/8 – 1-inch for your starting square, i.e. 5″ square equals a 4″ half-square triangle. If you are using 4″ half-square triangles your pinwheel will be a 7 1/2 inch square before it’s in your quilt and 7 inches once it is sewn into your project. You can use the chart below to help you figure out what size your block will be.
