Pack mortar in tight with a bit of wood on these when building up the

I forgot to add - when I did my wall extension, I also inverted the new
bricks where they keyed in so I had a frog facing a frog - fully packed
with mortar.

That's probably over engineered for a full doorway bricking up but as I
was adding a little wibbly bit on the end of a wall, it was necessary to
make the joint really solid...
