1) Start out by squeezing the Italian Charm between the flat part of your thumb and the flat part of your index
finger . Squeeze tightly.
2) Push your thumb forward, while still squeezing. You will notice
as you push forward that part of the Italian Charm slides with your thumb and part of the Italian Charm stays with
your index finger. This is opening the Italian Charm up. Now, since it is spring-loaded, don't let up on the
pressure or it will snap back into place. If you look at the part under your thumb, you will notice you have pushed out a flat hook.
3) Holding another Italian Charm in your other hand, you can
connect the "hook" to the "bar" on the back of the other Italian Charm. You don't have to open the other Italian Charm up, you can just hook right onto it. If you push on the Italian Charm to open it and nothing happens, turn it around and push the other way - they only open one way.
