Are you superstitious?

I'm doing a book of illustrations on habits of superstitions for Advanced Illustration Studio with David Tillinghast. It was a lot of fun to try and illustrate some superstitions because there are some really weird ones. 

Don't cut your hair outside. If a bird uses it to build its nest, you will have headaches.

Moles on the back mean money by the sack. 

Finally one I already knew: it's bad luck to open umbrellas indoors. 

More to come...
