Since last year was my first year in my own classroom, I went label CRAZY! I teach pre-k, but many of these could be applicable to any of the primary grades. I printed some of them out at half-size (e.g., the materials labels) and laminated them - most were attached to the Lakeshore blue bins on shelves/in cubbies! Some I printed at full-size (math center, literacy center, etc.) and laminated to post on the wall. I like all of my labels to have similar font and image styles so everything looks uniform.
