Here is a sample video and written instructions for making a self-contained incense holder made from a plastic bottle. It is the coolest incense holder I have ever used. The idea is not mine. An American lay person had one at his dorm room and I thought it was the coolest thing since sliced bread. I made mine in minutes. The Problem: No matter how you slice it, incense holders often let the ashes fall outside of the “catching-base.” It makes a mess and might be a fire-hazard too.
