1. Wrap a strip of paper around your finger where you'd like your ring to be.

 Tips & Tricks

Measure your fingers at the end of the day when they're at their largest. Cold weather can shrink your fingers up to half size, so make sure they're warm.

Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
