How to Make Incense
Most of my exposure to incense comes from the Nag Champa purchased by friends from the local head shop new age store. Apparently you can also get a variety of scent experieces by making your own. Scents of Earth shows you how to make incense, offering a detailed explaination of the difference between combustible and non-combustible incense, heating methods, and a complete list of ingredients with a few incense recipes. This is slightly self-serving since they also sell the materials, but the info appears to be solid.
