How to Sew the Traditional Kansas Star Quilt Block – a Free Tutorial

    The Kansas Star (or Crystal Star) quilt block is a classic block that first appeared in print in the Kansas City Star publication. The block is made entirely of square in a square patches so it is easy to sew together. Let’s get started!

    Sewing Directions:

    Square in a Square Units:

    Step 1:

    Using a Medium/Print 4.5″ square and four Light/White 2.5″ squares, sew together a Square in a Square patch. You can find my detailed tutorial for making a basic Square in a Square block at https://quiltembroiderypdf.com/how-to-sew-a-basic-square-in-a-square-block. In the picture below you can see the first four steps.

    Step 4:

    Using the Light/White 4.5″ squares, the Medium/Blue 2.5″ squares, and the Dark/Purple 2.5″ squares sew together four White/Blue/Purple Square in a Square patches like the ones shown in the picture below. Note the placement of the 2.5″ squares.

    Putting It All Together:

    Step 5:

    Lay out the five Print/White square in a square patches and the four White/Blue/Purple square in a square patches as shown in the picture below. From here the block goes together like a basic Nine Patch block.

    Step 6:

    Sew the patches into three rows as shown below. This is the hardest part of this block – getting those points to meet. Just take your time and don’t worry if they’re not perfect (mine certainly aren’t!).

    Press the seam allowances toward the Print/Blue/Purple square in a square units.

    Layout Suggestions:

    Here’s your basic 4 x 4 layout. It’s a little too busy for my taste. Although you do get the darker star and a lighter star (the medium blue points) showing up.

    And here is that basic 4 x 4 layout but with dark sashing and light cornerstones added. 

    quilt 2

    In this example, I added in a pieced sashing and cornerstones to get another star to appear (the medium blue star). This also creates a light area for some fancy quilting!

    For this layout I alternated every other block with a modified blue and white “Stepping Stones” block. 

    quilt 4

    Here’s the same idea as the previous layout but it is set on-point with light setting triangles. 

    quilt 5

    For this example I’ve used the basic layout but put it on-point.

    quilt 7

    Here’s an on-point layout using the pieced border and cornerstones idea.

    quilt 6

    And here I’ve added sashing and cornerstone to the basic on-point layout.
