Start with two squares the same size.
Match right sides together and sew a 1/4" seam all the way around. Pivot with needle down at the corners.
Now slice them up, cutting on the diagonals.
This results in four almost-perfect HSTs.
For my pillow I used 3" squares which resulted in four 1.75 unfinished HST. A 5" charm square will make four 3" unfinished HST.
Edit: The method does create all bias edges. I didn't find that problematic, and actually found it helpful with the small squares. The extra give helped me line up my edges. If you are concerned with the bias, it would be best to use the traditional method.
Try it out. You'll never make them the old way again. Thanks Christie for showing me a better way to make HSTs!
- Squares sizes and unfinished HST sizes are listed in this post.
Edit: While I was very excited about this method the first time I tried it and with a couple other projects, I've returned to the old way of doing HST. I've just realized I'm not a fan of those bias edges. There are multiple ways to create HSTs. Choose the one that works best for you.
