A large piece of paper
Favorite quotes written or printed. (It helps to have them pre-cut out for quicker application)
Glue sticks
Decorating supplies: colored paper, pencils, crayons, stickers, etc...
(Oh my goodness they love glitter-glue o_O)
Simply glue the quotes onto the board and then decorate. You can use string to hang them as well.... or to attach quotes to the board as you can see below.
