Mounting Posters From Tina Kimbley, an elementary teacher from Long Island, New York: "I use the wax backed white plastic clips to hang up items outside and inside my classroom. In the beginning of the year, I line the wall outside of my classroom with staggered clips. It helps to pre-measure with a medium size (16 x 22?) piece of construction paper. The TRICK is to place them with the paper clip insert UP. I then use one piece of tape to attach a paperclip on the back center of my student's prize work. The paperclip fits right into the clip and I can take down a wall of student work in seconds. Then one of my students can carefully peel the tape off the back and replace the paper clip. Avoid all tears by placing a piece of tape down first then another to hold the paper clip."
