Hello Summer Bulletin Board Decoration Big Island Beach Style Cutouts for Classroom Summer Theme Bulletin Board for Home Office Blackboard Wall Decor

Personally, I don't like 3-d decorations like leis or lanterns, because they look messy quickly. I'd go for a cheerful paper/ border combination on the bulletin boards (ie light blue/yellow for summer), and a themed set of decorations like these.. Once the kids are there, you can replace the pre-printed decorations with their projects.
