Oh, I love that spiral coil, Lilly!
I never thought of putting a flesh tunnel in my dreads, but I love it! I tried filling a hole by tying in a 25 peseta coin once. It didn't work too well. :(
A few of my things are this coil that I made:

A wrap from a salvaged friendship bracelet and some seed beads:

A glass bead my mom made for me back when I had my first set that lasted like a month:

Another one of Mom's beads:

And a question - I've finally convinced my mom to start making dread beads to sell at the farmer's market. Is 1/2" (12mm) a good size? That's too big for me but I think my dreads tend to run on the small side.
