My not-perfect but not-terrible solution is this nail polish rack I bought on Amazon.
The tiers give palettes a place to sit while still showing off how pretty they are, but as you can probably see, the buckles on the front of the Conspiracy palette don't let it sit perfectly flat. Also, I'm pretty sure I put the damn thing together wrong.
I'd like to upgrade to this bad boy, but it's quite pricey for my blood.
