I want to put a path down the centre of my allotment and contain it
within a wooden framework.

I am thinking of using long lengths of gravel boards, on either side of
the path, that are 6" x 1" and screwing these onto 2ft 6" stakes that I
will hammer into the ground. Is this a good way to go?

The stakes are 2" x 2" and I am thinking of cutting the ends to a 45
degree angle so as to ease them into the ground when I hammer them in.
Is this good or would a shallower angle be better?
