Every red blooded male should do a little bricklaying now and then. Churchill became so good at it he joined the Guild of Bricklayers.
I have been fixing bits of the garden again with mortar and bricks. The thing that worries me is these round frogs. Why do some bricks have the rectangular prism form on one side? Why do some have three holes that go all the way through?
Is it not a big waste of mortar filling these holes? Perhaps you are not supposed to fill the holes. Is it so you don't have to waste time placing the brick the right way up?
Answers on a hod please.
