Simplified Line Weight for Drawing

I made the following handout for my 1st year students.  It supplements a lecture and white board demonstration of a few elements, but I thought there's enough info on its own to make it worth sharing as is.  In many ways it's LINE WEIGHT FOR DUMMIES as it doesn't come with the full theory and explanation behind it.  It's kind of a Mister Miyagi approach;  do this and eventually you'll know Karate.  Or something like that.
