Jesus Piece Cross Necklace

Use a piece of string or dental floss and wrap it around the base of your finger.

Use a pen to mark the point on the string where the end meets.

Use a ruler to measure the string.

Allow enough room to accommodate your knuckle.

Different fingers on the same and the opposite hand may have different sizes. Therefore, measure the specific finger on which you are planning to wear the ring.

Measure your finger at the end of the day when your finger is likely to be largest.
