In addition to Bob's last post, I use fishnet on the shelves in my curios for a more nautical look to the display. Another benefit of the fishnet is that it helps absorb some of the curio's light so that ones not on the top shelf are not subject to the brightest light. But with the double flood lights with a built in dimmer, I can still have enough light to enjoy them.

Just an idea, although I don't feel the halogen lighting is as dangerous for the fading, but is still a concern for protecting my pieces.
