I bashed it out with Big'Ammer on the tree stump. Shallow as i wanted to make a design that showed all on the inside rather than on the sides, here i have also hammered it all over with my best hammer to give an all over dimpled finish. This makes it curl up somewhat, so it need annealing again. Before the rubber hammer sets it back to a bowl shape.
And there it is bowl shaped once more, with its edge rolled neatly!
Now it looks very shallow but that just right. Look the sun came out briefly.
