For those of you struggling with your color choices, here are a couple of resources that I use in both my sewing and my jewelry.
1.
Design-Seeds.com - http://www.design-seeds.com/ Look for the palette search link to browse palettes of your favorite colors. I've subscribed to their daily emailed palettes and save my favorite to browse later when I'm searching for color ideas. The site also has an amazing gallery of color palettes from thousands of photographs.
2.
Chip-it by Sherwin Williams - http://letschipit.com/ You can generate a detailed paint chip from a favorite photograph or graphic. For instance, I asked it for a paint chip of carriem's fabric choices shown her message (#16) on page 2 of this September thread and here's what I got.

I've even scanned or photographed a piece of fabric I'd like to use and generated a chip of colors that complement the fabric. I find it useful when stumped about which direction to take.
In general, I just go with my gut reaction to my choices. I find I like the results more often than not even if I didn't like them initially. These two resources are great "jumping off" places.
I hope this helps some of you still wrestling with color choices.
