Starting to paint them has highlighted a crucial error - I didn't leave any space between the bricks (and there was me thinking that I was being clever getting them so tightly together) so there isn't any space to see any mortar. In fact when I went to paint it, the bricks all gelled into one and you could hardly make out the pattern - aarghh!
I was a bit reluctant to start again so I've had a go at trying to 'fix' it. I traced the outline of the brick using a pencil which isn't ideal as the mortar now looks a bit shiny lol! Silly isn't it, I'm just typing this and suddenly thought why didn't I use a white or grey pencil (doh!)...
I do like this style of brickwork though, much better than my sandpaper bricks.
