Grate Holder Ideas (Nelp!)

Hello, I'm a relatively new egghead! I currently own a XL Egg and built a table for it. Image may be NSFW.
Clik here to view. I'm looking for some ideas on how to hang my grates. I have the regular grill grate that comes with the egg along with two cast iron moons (bought them today!). Image may be NSFW.
Clik here to view. I want to be able to hang them on this side of my table somehow. Image may be NSFW.
Clik here to view. I want something that will hold the cast iron grates but do not want it to look tacky. All ideas are welcome, Thanks!!
