Volunteer(s) needed Monday morning

While putting finishing touches on the classroom Friday night, I realized that I have lost my table signs (consisting of a red triangle, yellow square...).  I am hoping that a parent or two might be able to make these on Monday morning.  This should be a 30 - 45 minute chore.  The real challenges come in making a big circle, and in making a rainbow.

Let me know Monday morning if you can help out.
