Here is a super cute easy mail box I made with my 3-year-old daughter. We just purchased the pink mail box at Target for $1.00. Then I purchased some cute valentines paper and embellishments at my favorite scrapbook store in Blair Nebraska, A Paige to Remember. I have been to a ton of scrapbook stores but this one is just great and they have awesome classes too! Then my daughter and I glued on all the paper, felt hearts and words and flowers. Easy and Grace loves it. I keep putting in surprises and telling her she has mail when the little flag is up. She loves it!
