How do you put a picture in a heart necklace?

To put a picture in a heart necklace, first open the locket. Some heart lockets come with a removable insert shaped like the interior of the pendant. If yours does, remove the insert, place it on the photo, trace around it and then use the guidelines to cut out a heart. Should your locket not contain an insert, create a pattern out of a piece of cardstock or thick construction paper. Once you have the photo cut, insert one corner of the photo into the pendant first and smooth it into place with a toothpick. Repeat the process on the opposite corner diagonally and then slide the remaining corners into place. Work slowly to avoid scratching or creasing the photo.
