I am planning on making 2 structures: one is an actual free standing wall, 75cm long, 35cms high; the other a 25cm high garden retaining wall with garden bed soil abutting it. This will be 2 m long. I want the end effect to look like:
'purbeck random'
so it might not be 'dry' as such but with some retaining mortar.
Anyone done similar? Any tutorials on youtube? And hints and tips?
