Simply take a goblet ring and open it.
Attach whatever charm you want first.
Then add another (if you want), and another.
When you are done, make sure that everything is face up.
Place the open goblet ring around the glass and then close the ring.
Remove the wine marker when you are done drinking from the glass and carry it with you in your purse.
How's that for simple?
No glue guns, no measuring, jsut a quick assembly.
