Today is Pi day - 3.14 (March 14) so to celebrate I am going to tell you how to figure out how much binding you need for your circular projects like tree skirts. Use this anytime you need to figure out the outside measurement (circumference) of a circle.

Think way back to math class.

 Circumference = diameter x Pi

So.... measure the widest part of your circle (diameter) and multiply x 3.14 (Pi)

If your circle is 24" across multiplied by 3.14 you get 75.36". Add 5" or 6" for joining the ends (depending on how join could be more or less). You need about 81" of binding..... Easy!!

Don't forget to use bias binding when binding curves.

Enjoy some Pi today.
