Why I am Happy I Paid Attention in Math Class When Everyone Told Me I Would Never Use it Real Life.
Have you ever been crafting and needed to find the exact center of a circular object, and eyeballing it just didn't cut it? For example, when you want to find the circumference of a circular object without trying to finagle an uncooperative tape measure around it. I have used this little geometry tip a bunch of times, most recently when making a sunburst mirror and a lamp shade. It's very easy, I promise!
1. You will need a piece of paper, pencil, a ruler and your circular object. I am using a lamp shade ring in this example. If you can draw directly on your object, you can skip the paper and step 2 altogether.
