I never felt blank page anxiety, but im really struggling with expensive page anxiety. When im finally drawing on a "good" page im too afraid to fuck up and i cant enter the flow state needed for good, effortless looking ink lines.
Its not thats its really the price of the page that matters. I sketch a lot, 95% of my drawings are sketches and 95% of those sketches are very loose and messy. So one solution is to always draw on the same paper. But as i sad i sketch a lot. Using good Arches cotton paper for it, would be insane, would cost me hundreds of euros monthly and most of it would be garbage by design.
Drawing everything on shitty paper is a bad solution as well, the results are not as good, cheap paper turns yellow and looses its shape faster. And its very bad for mixed media. You add a little bit watercolor and its completely warped.
I wanted to start selling my drawing as well, but it looks cheap on bad paper.

It seams like a autistic non problem, and it maybe is. But gets annoying. Im not kidding, i still have "good" paper i bought over 10 years ago. A have expensive sketchbooks, that are laying for years unused, still wrapped in foil.
I think i have a light form of Hypergraphia, so in the same time completely filled hundreds if not thousands of cheap paper pages.
