First of all, take a 
Polystyrene cone in the desired size at hand. Make a glue dot with 
hot glue at the bottom of Polystyrene cone and start to wrap the wool cord 
around the cone. You should fix the string with hot glue in places to prevent it from slipping away later. In this way you can design the styrofoam pans 
in different sizes. Finally, a star is formed from 
silver wire, which should decorate the top of the Fir  
Tip: To get evenly shaped stars, you can take a Cut out form to help you and bend the wire around the form.
