Rob,

Awesome tute. I, like others are completely new to Gimp and was using Microsoft Publisher before this! (Don't laugh.)

I have gotten to the mountains stage and the directions are becomig a bit "ragged" so that I am having a hard time keeping up. I am stuck here:

Use the magic wand again to select the non-mountain area (like with the land) and create a new layer called “Mountains Mask” with a white on black. (Also the white colour selection as a new selection mask using Select->Save to Channel).
What does "with a white on black" mean?

What does the second sentence mean? How specifically do I do this?

In the land mask step, you selected then inverted the selection. Do I do the same here? Otherwise, my mask ends up with the mountains black instead of white like the land mass was?

I have repped you for this tute, it is very helpful!

My only complaint is how your directions started out very clear and step by step and then degraded, skipping key points or assuming the reader would know what you meant. Like you just wanted to be finished and rushed (which you probably did just want to be finished after all that work!)

Thanks for any help you can give.
