The Legend; Phil Hobson RIP
i use my spacers as wedges with ceramics on walls, the further you push them in the wider the joint. I keep an eye on my vertical joint consistency to keep lined up and a 1.8 level on top of each course for final check. A dodgy off square tile will throw you out anyway and the quality of some ceramics means constant adjustments.
Snap Mark, you just beat me, must be my age.
