TBH, I don't mess about too much in the ground, it might take a few course to get the bond right, and there may be one or two big or tight joints or cuts, but it's just not worth spending a lot of time on. If things work out, great, if not they will by the time it's above ground and seen. Full joints, plumb, level, square etc is really all that matters.
I might even have a big pile of rubbish in the garden too.
