So in this video, I want you to get out your calipers, or a ruler or some type of measuring tool and measure the widest knuckle on the ring finger that you want to use. So I'm going to get my calipers out here. And we want this to be in millimeters. So mine, my knuckle on my ring finger, the largest knuckle reads about 20 millimeters wide. So just remember that or whatever your number may be. Remember your number.

And so now that you've got your number, go ahead and keep that tucked away in your mind because we will be using it in the next video lesson where we create a ring to fit your actual finger.
