I'm looking to make something along this type of line design, but every time I try, it ends up looking very bad: messy instead of designery, uneven coverage, etc etc. I typically go for very geometric shapes (the two big design projects I'm currently working on are literally based on squares and hexagons), and I'm at a loss how to make tangled lines look good. I know about Bezier curves, obviously, and line smoothing, but that doesn't seem to be helping as much as I would like.
Are there any scripts out there that might help me? Or would you have any other suggestions on how to tackle this?
(FYI, I use CorelDRAW, sometimes with a graphics tablet, but if I absolutely need to, I can install Photoshop and give that a try)
