Ive tried a couple of different sites and these actually work pretty good but you will have to practice with the scaling so it comes out the right size.
Have fun,
that tutorial is more for web graphics
I'd doubt you'd get decent results when you print it...
you can scale it up, but then it will look like weird graded checkers instead of having a carbon look
don't care if you call is scaling or making it in another dpi/ppi
it "looks" like carbon in 4x4 pixels on your monitor
if you print and still think it looks like carbon, well... I guess you never saw real carbon before :Big Laugh
