Tip1 - Always, always, always use natural light. Unless you've got a tungsten balanced professional light kit or box, shoot your photos in natural light. It will keep your colors true, and add a certain warmth that you just can't get from an artificial light source. It is best if the light isn't too direct, as that can cause harsh funky shadows, and/or a washed out look. An overcast day is great, or late afternoon or early morning when the sun isn't directly over head. If you can't go outside, shoot your photos in a light filled room near a sunny window.
Tip2 - Never, never, never use your flash. It just looks bad. It changes the colors and causes weird glares, reflections, and hot spots. Do yourself a favor and turn the flash off.This picture was taken inside, using a flash, (the project is the Drop Leaf Scarf, free download page here):

Even after reading through the techniques suggested in the article, I'll likely just grab the camera, shoot a picture, and be thoroughly relieved that it downloaded to the computer. No one is paying me for doing this, after all. :o)
