Shame on 3rd period

Students in my 3rd period class have lost painting privileges today, unless they are to write the following statement 3 times on notebook paper. 

'I know better than to disrespect Art supplies in my Art Class. I know that I am responsible to wash out my brushes and put away supplies. Mrs Caddell is not my mother and shouldn't have to clean up after me. I also know that if I see others acting non responsibly, I am just as guilty not saying something.' 

PAPER MACHE - Art 2

FRIDAY IS THE LAST DAY FOR PAPER MACHE, unless by some miracle whatever is left by the end of the day is still usable by Monday. But don't count on it. I am not making anymore fresh stuff.
If you are behind, I suggest you actually get your artistic self to the Paper Mache table and put your needed layers on before Friday! I will be here for Tutoring today after school. Use your time wisely!!!!
Don't tell me later that the two weeks that were given to you weren't enough time when you don't even have a layer of it on your mask.

Sorry for sound harsh, but it's tiring me to see those of you who are wasting your time on this simple fun project.
