Even though I'm more of a digital artist, I love working with ink. There's just something about bold, permanent black that I just love. I also find that drawing with something so permanent can be more fun; you have to learn how to incorporate your mistakes into the finished piece, and often as a result end up with something more interesting than you intended.
I don't do it often but I LOVE working with ink. Yes it's very unforgiving and basically perminant but that is what I love about it. If you mess up you HAVE to work it into the peice, you have to change the direction of your peice or at least your perception. It keeps you on your toes.
I feel the same way. I recently started using ink now that my standard drawing skills have come up to par. And this statement hits my thoughts on the bullseye. I wish soooo many times that I could just flicker that one little tenth of a centimeter line off, but nope, instead I have to sacrifice the entirety of the image by thickening the lines. Lol. But if you get used to it and get it right, ink is probably, in my opinion, one of the most beautiful art forms out there! ^_^
Oh yes >.< As a hobbyist, I only work with ink, especially when I do my line art. I especially want to work on comics but I'm finding that the inking IS the biggest hurdle, haha. I know I can pull off styles and work on anatomy, perspective, etc. quite easily but proper inking technique is the most difficult skill to learn, haha.
Let's not forget people who do calligraphy, tattooing and other similar crafts involving ink.
There's something about ink that's so permanent and rigid and, yes, unforgiving. If you make a mistake, the mistake screams at you, haha.
