colors disappearing on uploaded Gimp files

Hey,
I am new at this, but finally making a little headway with Gimp. I have made some textures and they are uploading successfully and in the preview, they look fine. However, when I apply the texture, some of the colors are lost. For instance, I made a simple framed card with text. The background color was good, and the lettering was clear, but the frame that i had applied was gone. It was a simple brown line around the edge of the texture (256x256) which was there on the upload preview, but gone when I applied the texture to a simple 1.5x1.5 plywood board. Any ideas of what I may have done wrong? I was using the Mermaid Dairy's tutorial.
Thx,
BT

Did you check the Repeats parameters in the Textures window of Edit? If the Repeats parameters are less than 1.0, your border may be lapping off the edges of the prim you are applying the texture to. Try setting them to something slightly larger than 1.0 and see what happens.
