What's the style called for "Blinds?" It looks like you use a single stroke and don't take your pen off the paper till you're done, is that correct?
That is exactly correct. "Blinds" is under the "one-line" category, and you'll notice I've become partially addicted to that style recently!
I try to dabble in multiple art styles that I'm trying to become better experienced in, as opposed to just sticking with one or two categories. That wouldn't be any fun, in my opinion.
