So, I built some plant stands based on designs Halyna found on a couple shopping sites. They looked incredibly simple yet sophisticated so I felt it was a perfect weekend project.
Here are a few more details and one with the plant in it:
The wood is untreated 1x2 and 2x2 poplar. What really helped was getting nice hardware. The screws are gold triple-coated 2” torq head self-drilling (but I still pre-drilled) and the inside hardware is similarly gold plated. They are very sturdy and should look particularly nice when we add a simple coat of poly.
