Isn't it just so cool!? You'll need your pretties kit and some ribbon for this. The one I'm making I'm using burgundy and olive grosgrain ribbon.
You can layer your ornaments any way you choose, I'm going to show you how I like to do them then you can customize them any way you want. To start sting a pearl and your ribbon on your hat pin.
Fold your ribbon over to make a loop then string it on your hat pin again.
Follow that with another pearl, loop the ribbon, pearl, ribbon, pearl, ribbon, get the idea.
Finish it off with a pearl and a crystal one and put the bottom back on the hat pin. Use some silver cord and tie it to the loop at the top of the hat pin to hang it on the tree.
