It grew around a bottle cap

Nearly a year ago, I bought a bottle cap pendant from the seller in the booth next to mine at the Discovery World Holiday Artisan Market. I told her at the time that I'd tat it into something.  
Well, now I have!

I added some gears into the necklace by joining into them with normal joins while tatting.

By fiddling around with the ring, I discovered that the tatted ring could be easily maneuvered to lie under the gear, so the gear would be prominent on top of the tatting.

I decided to call this design Newcastle because that was written on the other side of the bottle cap.
