How to Make 8 Half-Square Triangles at Once: The Magic 8 Method
Making the Magic 8 work for you.
To make a Magic 8, first determine what size finished half-square triangles are desired.
- Let’s say you want to make 3” finished half-square triangles.
- Add to your 3” measurement, 7/8”. (Your total is now 3-7/8”)
- Multiply your total of 3-7/8” by 2. (That equals 7-3/4”)
- 7-3/4” squares are the size needed to make your 3” finished half-square triangles.
Cut two squares the desired size based on the formula above.
With right sides together, draw two diagonal lines corner to corner.
Stitch a quarter inch of either side of both drawn lines.
Carefully cut apart with out shifting the stitched fabric square.
There will be four cuts:
Cut 1: Vertical cut right down the center.
Cut 2: Cut down the center horizontally.
Cuts 3 and 4: Cut on both the drawn diagonal lines.
Voila! Here’s a look at some pinwheels made using the Magic 8 method.
Half-square triangles are often used in many quilt blocks and quilt patterns. Pinwheels, charm quilts and many star blocks to name a few. Just imagine how this simple and fast Magic 8 method will change your quilting life!
