INSIDE: How To Make A Perfect Ohio Star Quilt Block

I first met the Ohio Star Quilt block at QuiltCon 2015. I was attending Heather Jones’ lecture and she was sharing slides of her most popular quilts.

When she stopped on this one (affiliate) I fell in love with quilting, quilt blocks, modern quilting, and the Ohio Star Quilt Block. That’s all it took. One image and I was undone.

The history of the Ohio Star is not very clear. Many believe it’s history is rooted in the American Civil War. I was unable to verify this, but did discover that this block was extremely popular until the 1930s.

This leads me to conclude that the Ohio Star is one of the most iconic American blocks. And, it continues to be popular today with modern quilters.

Step 2 – Half Square Triangles

The Ohio Star Quilt Block starts with Quarter Square Triangles (QST). To make a QST you will first need to know how to make a Half Square Triangle (HST).

  1. Place a light and a dark fabric square right sides together.
  2. Use a pencil or water soluble marker, draw a diagonal line from one corner to the opposite corner. Personally, I prefer a pencil, but this will ultimately depend on the fabric you’re using.
  3. On both sides of the diagonal line, stitch a scant 1/4″ seam.
  4. Using an acrylic quilter’s ruler and rotary cutter, cut along the pencil line.

Make one pair of HST’s from the 5.5″ turquoise fabric and 5.5″ white fabric.
Make one pair of HST from the 5.5″ turquoise fabric and 5.5″ pink fabric.
Press the seams towards the darker fabric. I like to use the Clover Roll and Press to avoid ironing until I’m finished.

Step 3 – Quarter Square Triangles

  1. To make a QST take two HST’s and place them right sides together with opposite colors touching.
  2. Use a pencil or water soluble marker and draw a line from corner to corner, bisecting the HST seam.
  3. On both sides of the diagonal line, stitch a scant 1/4″ seam.
  4. Using an acrylic quilter’s ruler and rotary cutter, cut along the pencil line.

  • Draw a diagonal line from corner to corner, opposite of the previous seam. Be sure to nest the seam allowance.
  • Using a scant 1/4″ seam allowance, stitch on both sides of the mark.
  • Cut on the line. Say a little prayer and open up your QST. Press.
  • Trim each square to 4.5″ using a square ruler with clear markings like this Creative Grids Ruler. (affiliate)

Step 4 – Creating the Block

Now comes the fun part – when your block comes together. As you can see, when laid out it’s a simple nine patch block.

Assemble the block using the image below as a guide. Be sure to nest seams as you connect the rows together. Pay close attention to where the points meet.

Quilt Inspiration

If you really love this block, I have a couple of quilt ideas for you. The first is a modern version with lots of negative space. Don’t you love how this traditional block that dates back well into the 1800s can still look fresh and modern?

The second quilt idea is more traditional, but I’ve used modern fabrics. What I love about this design is all of the secondary designs that get built in. Notice the diamonds and four-patch squares. Imagine all of the quilting possibilities.
