I have traced through the Burrow, Flutter, and Frolic brush pen styles from Lettering in the Whimsical Woodlands. I am still having issues slowing down and avoiding falling into strokes I would use for Copperplate. These styles are loose, but not out of control. They are also more open and can stray from the baseline. This makes it more imperative to maintain balance between a flowing appearance and actually going too quickly.
I am moving on to drawing/illustrations. It has me giggling. You will see why next week.
