TIPS:
Some cans will enable you to use a can-opener on both ends, which can eliminate the need for a drill, and make the project even simpler, without affecting the end result, especially when using a diffusion covering.
Skip painting the interior of the cans white if desired. The light will not be quite as bright, but still excellent.
Our friend Ron at Farbulous Creations has created a fantastic, detailed video and PDF instruction for this. Ron’s thoughtful video covers so many facets and variables of this project, removing any guesswork.
