The type of pencil you get makes a difference as well. Inktense pencils are basically watercolors made in pencil form. You can apply to the front or back of the fabric. You apply the pigment with the pencil then add a liquid to get it to behave like a watercolor or paint and to help set it (if you aren't doing a heat set). Some people use aloe vera gel so the color doesn't bleed/wick away into adjacent areas as readily due to the gels viscosity. If you blend them with water or aloe vera gel they can then be heat set with an iron. If you don't want to heat set then use a fabric medium. There are tons of blogs, images and how to's out in the blogosphere. Just google it.
Edited to add you can also color with wax crayons and then apply an iron (with pressing cloth or newspaper to absorb the excess wax). But you can't color with regular colored pencils you would get at walmart unless they are the kind that will react with a liquid.
