We are redoing the end of the garden, and right at the end will be some
gravel of some sort, then a flower bed in front of the fence. We want some
edging stones (they generally seem to be 600mmx150x50) to seperate the
flower bed from the gravel, and was wondering the best way of laying these.
The flower bed will probably be a couple of inches above the gravel. Do they
really need to be set on a concrete base (the soil is quite a heavy clay
type) ? Any tips gladly received :-)

cheers
