If you don’t like cutting and stitching loose triangles together on the bias, or need to make lots and lots of half-square triangles for a quilting project, here’s a quick and easy solution.

## Making the Magic 8 work for you.

### Step 1:

To make a Magic 8, first determine what size ** finished** half-square triangles are desired.

For example:

- Let’s say you want to make 3”
half-square triangles.*finished* - 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”
half-square triangles.*finished*

### Step 2:

Cut two squares the desired size based on the formula above.

### Step 3:

With right sides together, draw two diagonal lines corner to corner.

### Step 4:

Stitch a quarter inch of either side of both drawn lines.

### Step 5:

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!

if you add 7/8″ for finished 3″ blocks, what is the formula for larger ones please?

Where was this method when I was struggling to figure out how to make a flying geese for my grandsons quilt.

What an absolutely wonderful method! Stash the ones you do not use and make something unusual and original.

I need a 2″ hst. Added 7/8 to the 2″ which made it 2 7/8. Then multiplied by 2. Equals 5 3/4″ square.

The finished product was much larger than 2″. What is the correct formula?
