I haven't used technical pens since I was in high school. Since I don't draw consistently, I didn't want to put ink in my technical pens. These were done with fine-liners, which don't make a super crisp line.

Here is the first worksheet, which is messy because I didn't want to print out the ones supplied for the class.

The second worksheet was fun to make. The line effects on the spherical forms look good, each in their own way. The colors I used with different mediums and the pens are a bit dull and the ink wasn't quite dry on the watercolor marker when it was placed over the ink. Opps.

For the small drawing, I realized that I kept picking up the smallest nib pens; I gravitate towards tiny, fine lines. 

This was a fun class!
