One word: FOLDERS.
They can be manila or bedazzled, but you need them to keep up with the sheer amount of in-coming paperwork! If you have more than one child in school, you need one for each child and perhaps one for special activities that have an excessive amount of paperwork. Although many activities are going more paperless, there are some things that just can't be avoided. Before you end up with a cluttered mess on your counter or desk, invest in a few inexpensive folders to makes things more manageable.
