Rob A did a nice tutorial in another thread on Gimp showing regional maps.

I've gone line by line on that tutorial in effort to create something similar, but each time I open a new layer it wipes the old one???

I admit I have limited tech knowledge which is why I came there something I'm missing? Aren't the layers supposed to stack, and where to I go to find previous ones.

I gotta admit, I'm feeling kind of a hopeless cause on this one...a little frustrated. Because I'm technically inept I can't even really describe what I've done...

GRRR - any input - shot in the dark, I know.
