Being an art on a cart teacher, I needed more organization. I searched for the perfect cart, ordered one and it still wasn't right. I thought about my needs and just decided to design my own. Thankfully I have a very talented husband who was able to make my ideas come to life. With a little organization supplies from Lowe's and IKEA, it's perfect. I think I may need to market this. It would work as a great mobile organizational unit for any teacher.
