When I was tidying up I recently rescued those old, no longer beautiful looking, round boxes from the attic. You are, of course, crying out for a new feature and makeover. Tadaaa ... in a few steps you can make a wonderful planter from this.
In principle, the whole thing is not that difficult, you should just be extremely careful not to burn your fingers on the hot glue. It happened to me several times. Ouch. Maybe gloves would have been appropriate here.
