I use this method of making bias binding...

Somewhere I saw a calculation to determine how much bias binding you'll end up with depending on the size of the initial square, and the width of your strips, but for the life of me, I can't find the formula again so I end up with alot more than I need, or worse am short a few inches.

Anyone know the formula that I'm thinking of?
