I'm kinda jealous of the writing samples here. I rarely used cursive, but my printing was excellent due to an old-style drafting class. Which also gave me the tendency to write in small caps--imagine that. But, over time, my printing lapsed, to the point that I had a hard time reading my own printing.
As for my signature, it's basically "First letter of first name, scribble, space, First letter of last name, scribble." I'm ashamed of it.
