This month’s tip is the formula for determining how much fabric you will need to create a length of bias strip.

First determine the width that you want the bias strip to be.

HINT: There are so many uses for these strips that I recommend getting extra fabric whenever you buy fabric so that you can make some strips.

HINT: Don’t cut the strips until you are ready to use them as the width will change with the usage.

Here is the formula:

Multiply the Desired Length of the Strip times the Width of the Strip and Take the Square Root of this. The answer will be the width and length of fabric needed.

Here’s an example:

I need 100 inches of 3 inch wide bias strip for my latest project.

√100 * 3 = 17.32 inch square of fabric.

So a 17.32 inch square of fabric will make 100 inches of 3 inch wide bias strips.
