thanks for the search post. I still haven't found the post I saw. Really strange, I've never had this problem before.
I have seen some on family handyman website. you might check there. Also on Ron Hazelton website.
I finally found the pantry with the shelves but it was on Pinterest. I will try to post a picture of it. It was on Shelf Genie of Dallas.
