What would be the best (preferably free) way to go about creating a skybox texture from scratch?

I'm mainly concerned with creating the actual image, in the right shape so that it doesn't turn out distorted; I can find out how to put it in game later.

A couple of paint-over .psd templates have been posted on the site:

Simple grid template, image is broken but the DL still works. GIMP can import and edit this.

More complex template that takes advantage of 3D texture mapping. I don't know if this works in GIMP, so you may have to get Photoshop for this one.

Oh wow! I saw the psd template but I never came across the grid. That's really useful idea!

The 3D photoshop template is interesting, (and yes, beyond gimp's capabilities). What I would do is model the skybox in blender and render it out with 6 cameras. Blender has (primitive) texture painting that you could use to block out clouds and other non-modelable details.

If anyone knows a GIMP script that I could use to distort an image like Ravidge's grid texture, that would be most useful to me. Something like a bulge effect that only affects y values.
