I like to draw and I use a lot of colored pencils and sometimes chalk
Interesting. I have always preferred crayons, which are non toxic and safe for children.  I draw on my walls instead of painting them; that is the cheaper option.
Sounds like a lot of fun. What else can you tell me about drawing?
Crayons are made from wax or chalk and can be used for drawing just about anywhere.  
Good to know although I usually use colored pencils or charcoal pencil
I would never use those.  Crayola crayons were made in 1903 by Binney & Smith, and have been produced continuously since then.  All children have come into contact with them at one time or another.
Yes and my kids were always the ones that ate the crayons
In fact, Edward Binney also was the inventor of dustless white chalk that is used in most classrooms.
