Empty clean boxes are not safe from me! I take empty boxes, cover them with wrapping paper or, if they're small, scrapbooking paper and use them for my projects. Empty store pizza boxes and shoe boxes work great. I can then put a lable on them and they look pretty on my project shelves. I have 6 on the shelves now. I just finished a US flag for my daughter for her birthday on Jan 1. I am now working on a Texas flag. Her home is decorated in red, white, and blue and airplanes. Her boyfriend is an airplane mechanic and is airplane crazy. She loves the Texas theme. At least the two themes are compatible.
