The idea is large and laminated! Write the names creatively so they are both readable and pretty, using paintpens
Pawprint in your school colors
Large Heart with glitter border for Philanthropy Day (RMH is the house that Love Built!)
Depending on the theme of your video/skit (IE: If you are "A League of Their Own" then a large Baseball shape; if you are doing a movie like Annie, then everyone can wear large silver, black and red stars lined in glitter, or a ticket-shaped nametag)
Prefs-- large white diamonds with a pearl border. Where the diamond points come together, glue a small purple violet
Hope this helps! Larger nametags with minimal detail are classy, pretty and uncluttered. The PM should be able to read the name clearly. If you hold a position, indicate what it is!

PM me; I have lots of ideas!
