We have some of the business card magnets at school and I'd like to create a magnet for each student to use to make their daily 5 choices each day. 2 years ago I ordered some from vistaprint, but they came with a decorative background already. The ones we have at school have the adhesive. What would be best to stick to it? I need something that will last a year. I'm not sure that regular or scrapbook paper would hold up. Any ideas or has anyone done something similar?
