If you need to make a ton of Half Square Triangles the Magic 8 Method is the way to go! For this week’s installment of the Half Square Triangle Tutorial Series, I will show you all how to make eight half square triangles at one time! This one is great for making lots of them at one time and also if you are making a quilt that uses several blocks with one fabric or print like pinwheels or turnstiles.
I just love all the color combinations that can be mixed and matched and almost any fabric looks good in a half square triangle block. They are also super fast and the quilt combinations are endless. You can see the rest of the series here:

The Magic 8 Half Square Triangle Tutorial
1. To make HST place two equal size squares of fabric Right Sides Together (RST). It is much easier with this method, to make the squares 1/2in to 1 inch bigger than you would like the resulting square to be. Mark a diagonal line across both diagonals on the wrong side of the top fabric square.
2. Sew a scant 1/4in seam on both sides of the marked diagonal lines.
3. Using your rotary blade, cut the square into eighths as pictured above. You will cut a horizontal line, vertical line, and on both diagonal lines. following the drawn diagonal lines.
4. You will now have 8 Half Square Triangle Blocks.
5. Open the blocks outward and either lightly finger press or use your iron to lightly press. Be very careful to only press up and down, NOT back and forth so as not to stretch them..
4. Your seam should be pressed (both layers) toward the darker color.
6. Place a ruler on the block keeping the 45-degree diagonal line over the diagonal seam. Trim each side of your square to the desired size.
7. Easy peasy! You now have finished half square triangle blocks ready to assemble in a quilt top.
Next week I will be sharing the fabric strip method as well as the triangle paper method. And finally all the quilt math and cutting tips and tricks you need to make perfect Half Square Triangles.
But don’t worry, I will be sneaking some other sewing projects and tutorials in between because let’s be honest, there are just so many things to sew and while Half Square Triangles are lots of fun to make I wouldn’t want you to get bored only seeing those!
