I found this site several months ago:
http://momath.org/home/math-monday-08-16-10/. This should "tie in" with your accounting degree. I've been sewing 53yrs, and am a self-taught quilter. It's a part of my creativity process and a great "stress buster". Good luck on your presentation! I am sure you will do great! God Bless! and congratulations on all your hard work and education!
