favorite tote bag

This bag is perfect. I tutor math at the local community college so the design fits. The bag has gotten all kinds of attention not just from my students and coworkers, either. The fact I can explain a lot of what's on the bag impresses folks who admire it. The fabric and construction are top quality as well.
