Mason Miller Bean, I think to do it right and have it look good at the end of the day, you'll want to have a carpenter or a custom cabinet shop do your project. There is really nothing on the market, that I have seen at least, which makes this possible.
That being said, there are lots of ways you could do this if you are very handy and have the right tools and lots of patience: I've seen people attach a horizontal support to the studs for the length of shelf and then dado out a section of the shelf and then screw vertically into the horizontal support. I'm not sure how much load you could put on the shelves in this scenario tho...sorry, this probably doesn't help you too much!

beanthehairstylist Thanks anyways, we will find a way. Not looking to put anything on it other than spices. It's really just for show. Bean
