That paper airplane you folded the other day...please get that out.
Please also get out your sketchbook and a pen.
You should do one of two things at this point.
Option One: Pile all the planes from your table up together and draw this.
Option Two: Take just your paper plane and draw a blind contour (in pen) of it many times, and of various sizes on a page in your sketchbook.
Please again gently save your plane and we will use it again on Friday.
