This pattern require a bell and beads as charms and embellishments. Good luck to the groom and his future wife. This charm is sterling silver but if you want just one like it for cheap price go to ETSY.COM
there is a lot of them and you can choose what you like. I think the beads will be around where the flowers are. When you get the pattern it will show you where exactly you add your beads.

The beads that you need for this project are sold on this website here. Click on the link for Beads and Charms on the left and it will take you to the page where you can order them. They are $1.30 per bag. As best I can tell they are placed around in the vines. The instructions will tell you. Hope this helps.
