'biners would be a good idea. I'm thinking more about the bands still... imagine a pre-made piece of metal, the circumference of the corney, with a loop of wire around the end of it... make it ... 1.5" tall. thread it through the wire loop and hammer closed for a permanent and hopefully tight fit. dunno if it's feasible though.

i may just make some plates and hang them with the corneys. or stencils and spraypaint.
