It started with one pothos
The plants came first. The hangers came because nothing I could buy was the right size, and the ones that fit fell apart the first time a wet pot went in them.
So I made one. Then I made one for the plant next to it, and by the time the window was full I had worked out how to make them properly, in cotton that holds its shape and takes a soaking.
The cuttings came later, and only because the plants themselves got out of hand. Everything I sell is something I already keep.
