Crystal Filled Mini Bottle Pendants

I have been experimenting a little with Borax crystals lately, I got one of the huge 4lb boxes so there's plenty to work with. I also had these bottles lying around that I bought for other projects I never really got around to. The crystals are a little difficult to break apart and fit into the bottles, but I made it work and I really like the end result.

I wanted to do a little more than just adding a loop to the cork, so I used some wire to add a swirl and a loop to the back. It took me a few tries (I'm very new to wire wrapping), but I got the hang of it.
