Yes, my friends, this is what we do in class here at Covenant College.
. . .
Let me explain.
...no, there is too much. Let me sum up.
We did an experiment in Drawing I this afternoon involving contour lines and markers.
Fear not, it is washable.
And yes, even though class got out at four, I kept the stripes 'til after dinner (which is now). ^-^
Edit: My summing up was not complete. For those who don't know, in high school I had a history of getting in trouble with my parents for drawing on myself. Thus, I found today's exercise particularly ironic. ("But Mom, Professor Carpender made me do it!")
