This gorgeous pyramid planter takes about 2 hours to make but is simple enough for a beginner.
It is very cheap to make as you can re-use pallets instead of purchasing new wood.
The only tools required are a square, pencil, electric/cordless drill and suitable spade end drill bit, and a tenon saw; although a chisel and some sand paper would be useful for tidying up the slip joints.
