I was wondering if two of the six allowed colors could possibly be mixed for a t-shirt; Y'know for shading and stuff. Thanks.

    When two colors overlap on a screenprint they can produce a third color variation but im guessing teefury doesn't do that. It would be next to impossible to determine exactly the hue and shade of the third color

    There are a few threads on a technique known as Halftone shading. Some of them are 'how to' threads by myself and Tuism (6-18-2011's featured artist who used the technique on his piece). 
     
    One of them which contains info from Jimiyo on keeping a non-Halftone version of your art. And I've spent hours doing one piece without considering keeping a version without the shading. 

    Bugger!
     
    Halftone shading is the ability to create intermediate shades or colors by using very fine dots. Just as a TV picture or a JPEG on a computer monitor looks like a seamless image at a distance, you can get gradients like this...

    ...with just two colors.

    I have also found the halftone shading technique in the link below pretty helpful. If shows how to do the halftone shading with lines instead of dots. Just one of a million ways to tackle shading. Hope this helps!

    Ooh, I was thinking of looking for a technique this wekend, as I was manually adding lines to an air cowling on a helicopter by manually drawing a few spaced lines, then copypasting them down the page and merging the levels.

    What I want to do is something in a technique called Intaglio.

    It's a way of adding shadow in the way an engraver would do it. Using a series of very fine repeated lines.

    M.C.Escher was the king of this.

    And if anyone can point me to a website that details how to shade like this using GIMP (or any other software), I'd be a happy camper. I can do it manually, but I'd love for their to be a way to duplicate the effect in software to give a whole piece that particular look (without needing 50+ hours to manually add the lines!).

    I guess there is a reason why actual etchings are still done the old fashioned way. the lines follow a suggestive pattern that on one hand shades the object, but it also gives it certain structure and depth effect. a computer can't do this by itself, because it cannot tell the depth or way the structure is supposed to flow to look good ... not from a 2 dimensional input that is.

    you could try and come up with a clever custom brush to reduce the work load ... but that's all I can think of, really

    bottom line: I haven't seen any convincing "digital etchings" that didn't involve a lot of manual wrist fraying detail work ...
