Forgive me Coby for not being clear. I'm very, very new to all of this, and appreciate the help.
To answer your questions:
• What says where to save them, SL or Gimp? - Gimp help page told me where to save them if I wanted them as a brush, which I was advised by one person is the best way, and another person not. At this point, I just want to get the textures period on.... >>> next question >>> • Apply them [the textures] to what? A mesh clothing template.
I've searched every day for a couple of weeks now on a tutorial on YouTube and I've been able to pick things up here and there, but the biggest thing holding me back from any progress on this project is knowing how to put the textures from SL onto the mesh clothing template.
Again, thanks for the help and patience.
