I think your rock set-up looks really good. Did you use all 50 pounds of the Pukani? Will you be adding sand?
do you have a build thread on your light hanger? it looks really nice.
Sorry, I do not have a build thread and I did not take any pictures. It was very simple to make though. It is made out of pine 2x2s. Just make an L out of the 2x2s and then cut some small peices and add them at the joint of the L to make a 45 degree angle. I will add some close up pictures later tonight if you are a visual person like myself.
