Knopfkater's sketchy world

[John]

I also thought about limiting my tools to "ink" only. It has some downsides but it would give the benefit of possibly improving faster by doing more, (and more obvious ) mistakes.

I agree with the notion where the mistakes are going to be more obvious. Doing things with ink only will definitely make you commit with the marks you make.

My apprehension would be: if I made an incorrect mark with ink, the tendency is to start all over again. Imagine you're halfway into getting it done and you make a bad mark.

I know people who render themselves into a corner and find a way to fix the piece with no erasures. It's probably a different exercise altogether. But I agree with Noodle. No point in limiting yourself if you're not getting anything out of it.
