Ohio Star Quilt Block Tutorial + Tips & Tricks

This blog introduces the Ohio Star quilt block, a classic and beginner-friendly design that dates back to the 1800s and uses simple techniques like half-square triangles and hourglass units. It explains how to construct the block step by step, from cutting 5 inch squares to forming the star layout with rotated units that create both hourglass and bow tie shapes. This post also highlights the versatility of the design, showing how different fabric combinations can change the look while keeping the process easy and approachable. 

This classic quilt block is called the Ohio Star, and it dates all the way back to the 1800s. It is a timeless design that is both simple and beginner-friendly, making it a great project if you are looking to build your quilting skills. Within this block, you will practice working with half-square triangles and learn how to create hourglass units, all while putting together a beautiful star pattern. 

The finished block measures about 11 inches. To begin, you will need solid squares for the center and the four corners. In this example, I used white for those areas to let the star design stand out. The rest of the block is made up of hourglass units, which are easier to create than they might look.

Start by cutting 5-inch squares of fabric. To make half-square triangles, place two squares right sides together, draw a diagonal line across the center, and stitch a quarter inch on both sides of that line. Cut along the line and press the pieces open. Now you have two half-square triangles. 

To turn those into hourglass units, take half-square triangles and place them right sides togehter, making sure the colors are opposite each other so the seams cross in the middle. Draw a diagonal line across the unit in the opposite direction of the original seam, then stitch a quarter inch on both sides of that line. Cut it apart and press it open. This creates the hourglass shape. If you use two pieces of the same fabric, you will get a single-color hourglass. If you mix fabrics, you will get a two-tone version, which adds a fun variation to the design. 

One of the great things about this block is how little fabric it requires. A single 5-inch square can yield multiple units, making it a perfect project for using up scraps. This is likely why the pattern became popular in earlier times when quilters worked with whatever materials they had available. 

The layout is straightforward. The center row features the hourglass units, while the top and bottom rows use those same units rotated to resemble bow tie shapes. Once everything is arranged, sew the pieces together row by row, then join the rows to complete the block.

You can choose to keep your hourglass units in matching colors for a more traditional look, or mix fabrics for a more dynamic and modern feel. Both approaches create a beautiful Ohio Star, so it simply comes down to your personal preference.

This is a wonderful block to add to your quilting repertoire. It is simple, versatile, and full of history. I hope you will give it a try, follow us on Facebook, subscribe to our YouTube channel, and as always, happy sewing.
