I'm not far off doing the same (blog update coming soon)
When marking out, how do you ensure it's square? I was marking out ours today and having got the two front corners in the right place, I then placed the back corners about right, what looked to be square. then followed a process of measuring diagonals and adjusting until they were equal. Takes a bit of time on your own. Are you going to tell me there;s an easier way?
When painting the lines to dig the trench to, I was planning to paint the two outside lines, not the centre. Is that just preference or is there a good reason to mark the centre instead?
Faye needs a bit more practice, bit it will come soon. In my case it's been good to practice on stuff that doesn't really matter much.
Not really an easy way to get square on your own apart from diagonals, one long winded way is to put a sheet of ply on the approximate corner, this allows you to use a much thinner line (pencil) to mark arcs from your two other points, once you get to that level of accuracy pythagoras can come in to play, you could also use 2 tape measures, but that does get quite fiddly on your own,
i m not overly fussed about being square to the party wall atm because i already have a major wall to run parallel with which is much more important for roofing it. the new gabel end wall will run square to my new wall to simplify fitting my kitchen, the building may not be a perfect square but considering i have 2 walls that have to stay standing it will be as good as i can get
as for painting 2 lines that is up to you, for the sake of digging in the right place guessing the centre between the 2 central teeth will be more than close enough so 1 line just saves paint and time
