I have extra necklace chains lying around, so I grabbed a gold one to match the tassel barrels.
The first order of business was to remove all the earring hooks from the tassels. I wasn't going to use them as earrings anyways.
With my trusty pliers, I opened the jump rings. Remember to always open jump rings sideways and not apart, so you don't break them!
Then, I hooked the tassels onto the chain, about 5 spaces apart.
