NATTARIOUS thanks for the hair spay trick. I know if you did chark pastals you know the old type that will smear all over the place and get on you if you touch it. I did some and was taught if you spay it with hair spay you fix it.[that is what they called it and was cheaper than the pastal spay called "fix it"]  It will not smear or get on you. The chark will stay where it at. 
Now if you have a heath touble You will need to wear a spay mask. Some people will have a reaction to the hair spay or at lest the type that was used 30 years ago. You bought up some old memories

what you see is not what you know; it in your face
