I'd like suggestions of what size (diameter) and wood type to use for a project I'm considering. I want to make macrame wall hangings that incorporate plant holders, so the rod would need to be strong enough to support the weight of the rope/cording material and the plants. A macrame panel 14"w x 30"l weighs approx 2 pounds and I estimate approximately 7 pounds for the planter/soil/plant. I'm considering making some that are three panels wide, so a total weight of approximately 30 pounds, preferably on a 48" rod. Also considering making single & double width hangings, on appropriately sized dowels, perhaps 18" & 36".
