I've got a flower bed which is edged with logs similar to those shown here
The logs are held together with two strands thick, stiff wire which are beginning to rust through, causing the whole thing to fall apart. The wires are attached to the backs of the logs with small 'U' shaped nails. They are not hammered into the earth but laid on patio slabs.
Does anybody know where I can get similar wire to repair these logs or maybe someone could suggest an alternative method of attaching them to each other?
