I hand draw cards using dip pens, ink, brushes, or whatever media is interesting. It’s a nice way to spend time, and art shops have a fascinating array of niche products. There’s a bit of consumerism there, since you’ve got to buy the supplies. But a few supplies goes a long way, and there’s not really the sort of expansion lock in that other products have. You’ll always want a new ink color or a different nib for some purpose, but you can get any brand you want. They don’t look great, but, uh, it’s the thought that counts?
