Happy 2007! May it be filled with loving, learning, and laughing!
I've just been puzzling over how to get my crayon line to be thinner. Figured that if I could type 500% in the tool size panel, I could also type 0.5%. But it doesn't accept fractions.
Then I realised that it's actually a matter of making the picture a higher resolution pic.
In other words, if you've got a low res pic -- say, 200 x 200 pixels -- your crayon tool on 1% thickness will be VERY fat.
In high res -- say 3000 x 3000 -- that same 1% crayon will have a very fine point indeed.
Just thought that might interest anyone who's been frustrated by not getting thin enough lines.
