Well, in that case, here's a link that shows what it would look like to cover a butter bowl with pebbles/aquarium gravel for a BP hide. It is a Gecko tank, and the background is covered in the way I mentioned. The pictures are at the top, and if you scroll down, the OP gives a link to the site he posted the build log on. The site he links to is in Russian, but if you continue to scroll, I posted a link to a translation. Hope that gives you ideas for inexpensive, custom hides!

EDIT: lmao, I forgot to put in the link!!!
