Attach the first flower to the end of the chain. To do this, you will need to form a loop on the nail. Place the ring with the charm against the hole and bend the nail shank at 90 degrees to the base of the hole at the top of the flower. Cut the shank back 8 mm from the corner.
Grab the end of the shank with the tip of the round-tipped pliers. Turn the pliers in the opposite direction of the angle so that the end of the nail is in a loop. If you are not familiar with this method, go to this data sheet: How to form a loop on a jewelry nail.
Before closing the ring completely, slide the end of the chain inside. The two other flowers will be fixed in the center of the chain and 4 links below the ear hook. You may have to force it a little because the links are tight.
