Fire Bowls
The centre of the garden.
Thirty five bowls, and they're all the same where it counts: 2mm raw steel, welded rather than bolted, unpainted.
The differences are in the shape. The Bali sits low, about 20cm, which is the one for cooking. The Haiti and the Viking run deeper, which is better for warmth. The Montana stands on legs with a log shelf underneath, and the Cuba, Square and Brasil are the 70x70cm square ones for gardens with straight lines in them.
Whichever you pick, it'll take a lid, grate or plate in the same diameter later, so the first purchase doesn't box you in.
