What's your favorite frag rack or DIY?

Hi everyone,
I have a handful of frags that just absolutely refuse to remain anywhere on my rock work. I don't want to glue them down, so what is your favorite frag rack or DIY solution to a frag holding system. I'm considering one of those in sink sponge holders, has anyone had success with those?

Oh this is a good one, i've got tons of scrap laying around. Guess I know what I'll be getting up to. Wish I would've thought to look more before placing an amazon order haha
