Halfway
So, halfway. It isn’t quick, but it does look good. The rhythm is always the same: cut a plank to size, glue the thread along the edge with it, press down, and on to the next. That explains the pace, and the Christmas days don’t really help either.
I think the caulking seams are actually just a touch too wide, but to the eye I find them pleasing like this. So I will try to make the other side as symmetrical as possible.

That will be a bit of a job, because the width of the planks varies roughly between 3.8 and 4.2 mm. With a bit of sorting and measuring I shall try to let the planks into the margin plank at the same height on both sides. Herby63 called that letting-in ‘joggling’ and thought precisely that part nicely done. An encouragement to do it exactly the same on the other side, even if it takes measuring each plank a few times before I find the right width.
