Large whiteboards, or dry erase boards, are one of the best tools for displaying and organizing information. Instead of buying them from the store, save yourself some money by making your own! Plastic and foam are inexpensive options for making a big board you can frame and hang on the wall. If you need something magnetic, try painting a steel sheet. You could also use paper and plastic to make small boards that are easy to carry around. Create a whiteboard to make notes, write down things you need to remember, and otherwise make life a little easier.
