The Sawtooth Star quilt block is a timeless and versatile design that has been popular in quilting for generations.

It’s both beginner-friendly and easily adaptable, making it a favorite for quilts of all styles, from traditional to modern. The Sawtooth Star features a central square surrounded by four star points and corner squares, forming an 8-pointed star.

The Sawtooth Star dates back to early American quilting and was used in many traditional quilt patterns.

(This post has been updated from a previous version, and a free, printable pattern for the block has been added).

Construction Methods

There are a few ways to create a Sawtooth Star block. Each of the variations deals with how the star points are constructed.

They can be made:

  • Using Eight Half Square Triangle Units
  • Four Flying Geese Units
  • In addition, the Flying Geese units can be constructed using the traditional or no-waste Flying Geese methods.

Today’s pattern features the traditional Flying Geese method. I prefer this method because it reduces the seams in the block (as compared to the half-square triangle method.

The no-waste flying geese method requires the units to be trimmed and squared up before constructing the block, so I prefer the traditional method, which requires less trimming.

Block Details

I used fabrics from my scrap bin for this block. I know they are no longer available to purchase, but I feel it is too wasteful not to sew with the fabric I already have just because you can not buy it. There are always SO many cute fabrics for sale; you should be able to find something that you love!

The gray fabric is Iron Confetti Cotton Solid by Riley Blake Designs. The center bunny fabric is from my Wonderland collection, and the small floral print is from my Fox Farm collection.

What Can I Make with a Sawtooth Star Quilt Block?

If you’re new here, I’m slowly working on making a sampler quilt with each block, a monochromatic color scheme, and gray background fabrics.

I have yet to decide on a final layout or number of blocks, but I will share both with you when I’m done.

In the meantime, if you’re looking for ideas for leftover quilt blocks (or single blocks), I have a complete list of Orphan (or Leftover) Quilt Block Projects.
