I made clouds to post above different sections in my elementary school library. I love the whimsical cloud shape. The titles are easy to see so the children can find what they want, and in smaller writing is additional information about what is in each section. I cut them out and use double sided tape to post them on the walls. Someone told me they are so cute that I should submit them for other people to use. I hope you like them.
These include three clouds: Biography, Biography (Presidents), and Fiction (for chapter books.)
I also made signs for the books in the DEWEY section of my library.
