Free Tutorial for the Sandhills Star (or Blossoming Cactus) Quilt Block

By: Elaine Huff

The Sandhills Star quilt block, steeped in tradition and sometimes referred to as the "Blossoming Cactus" block, was first published in the Kansas City Star. While obviously being a star block, it can also be considered a weathervane block.

Sandhills Star is composed of four fabric colors set against a contrasting background. Your color placement can change the entire look of the block so you can create a quilt that is uniquely your own. Let's take a look at how to construct this beautiful block!

(Update: Sandhills Star block pattern is now available for purchase at https://www.etsy.com/listing/1683605077/sandhills-star-block-pattern-pdf-quilt.)

Sewing Directions:

Hourglass Unit:

Step 1:

Using the Medium Gold and Dark Orange 5.5" squares, sew together an Hourglass unit like the one shown below. Trim/square up the unit to 4.5" square. You can find my detailed tutorial for making a basic Hourglass quilt block at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-hourglass-or-quarter-square-triangle-block. You will have an extra unit to use in the next block.

Layout Ideas:

Here is the basic 4 x 4 layout. The blocks create a lovely secondary design where they come together.

In this example, I've added in narrow sashing and cornerstones to give separation to each block. (It also eliminates having to match up points!)
quilt 2
For this layout, I changed up the color placement and added in an alternating chain block. I think this is my favorite!
quilt 3
And for this example we have an on-point layout with sashing and cornerstones in a complimentary color. Additionally, the setting triangles are the same fabric as the light color in the block.

Conclusion:

The Sandhills Star block was easy enough to sew together and creates a star block that is a little different with the four squares in the center of it. I had fun picking out colors and seeing that by changing the background to a medium color, a really different-looking block was created! All in all, a fun block to play with! You should give it a try.
