New Shirt Style

I have thought about sewing napkins on my shirts in the shoulder area.  I think it would sell well with people who have toddlers.  Elana has this habit.  I would say bad habit, but she is keeping her mouth clean.  If I get food on her mouth, when I feed her, she will take her mouth and clean it off on my shoulder.  If you see me with food stains on my shoulder, you know it was Elana.  I swear, I am not wiping my mouth on my own shoulder.  I am not just trying to blame my soon to be 3 year old.
