    There's linear, radial, spiral, etc modes for blend tool, but what if I want to use a curve or path to determine the blend shape?

    PS. Guys, your captcha sucks :p For quests posts it just doesnt work, I literally tried 15 times. and its set too difficult, my text was upside down [/rant]

    You can set the blend tool shape to "shaped" and make a selection from your path. Then make a stroke. I think this should give you your desired result.

    I can get that to work only on selections, not paths or curves

    Yeah, so if you've got a path, make a selection out of that path and then apply it :wilber:

    Hm... scroll out a lot and then close the path outside the canvas?

    That will cause only one "side" of the curve be selected, while i need the curve to be the "middle" of the gradient effect

    Well then ... take another approach:

    - Make your path
    - Make a new layer
    - Stroke your path with a big line
    - Go Filters > Blur > Gaussian Blur > Blur it by a good amount
    - Rightclick in the layers dialog > Alpha to selection
    - Make a new layer
    - Take the blend tool, select your desired options and try.

    I'm still thinking of a better way, I'm sure there is one...

    Not exactly what you want but maybe worth a look.

    Ofnuts ribbon-path from:

    http://gimp-path-tools.sourceforge.net/tools.shtml

    An example, http://i.imgur.com/6uF32.jpg

    This is just the same path duplicated a couple of times. Top is the original path, bottom is the path stroked.
    Center is the path converted into the ribbon, then path to selection, then a linear gradient applied left to right.

    Of course the gradient does not exactly follow the path, but I don't know what does.

    Other snag, if you use windows you will need Python 2.6 installed.
