I raided the recycling bin for today's project, a grocery list notepad. There's a magnet on the back so that it can hang on the fridge.
You could use the same concept to make a holiday wish list, a place to write phone messages, a to-do list, or anything else. It can hang from a filing cabinet or inside a locker. Affiliate links below.
Cereal Box Grocery List Notepad
Use scissors to cut out the letters to spell GROCERIES (or whatever title you want). Cut an extra strip from a cereal box that is the same width as the top of the notepad and long enough to hold the entire message.
Glue the letters to the cardboard strip, then glue the strip to the top of the notepad. Make sure you are adhering it only to the top strip and not to the paper itself.
Add a generous amount of magnetic tape to the back of the notepad.
Now all you need to do is to hang your list. Make sure there's a pen or pencil nearby. When it's time to go shopping, just tear off the top sheet and you're good to go.
