a few favorite drawing implements (favorite pen or pencil)
6 sheets (5x7 inches or so) of paper for collage (you may not use all the sheets)
medium and glue brush or glue stick
catalog or old magazine to be used for glue application
A glue stick may be fine but one might want something a little stronger like decoupage glue, PVA or matte medium.
Optional (bring only if you have it)
a box cutter for cutting off covers
an X-Acto knife and cutting mat
