Yes, indeed, the last pick isn’t in proper alignment.
Is this a problem? Actually, no. Because in point of fact, the pick will be set into place by the next pick woven.
This isn’t usually seen but I’ve spoken to other experienced weavers and the observation is that the beater just presses the pick into rough alignment and it is the weaving of the next pick that seats each pick properly in the cloth.
Since linen is stiff and wire-y, plus the weave structure is mostly a 1:3 twill, the tendency for the pick to pop up and away from the pick below is much more noticeable. A second beat is not required, just a slow steady consistent laying in of each and every pick. Subsequent picks press the pick below into place.
As for reed marks. I know a large number of people anguish over them, worry about putting more than one or two threads in a dent, fuss about the ‘streaks’ in the cloth. Personally I don’t worry about them overly much. Reed marks are not, in my lexicon, a ‘flaw’ but the foot prints of the loom in the cloth. Most time they disappear – or are greatly reduced – in the wet finishing. But not always. And if they don’t, I don’t worry about them much. They are, after all, consistent. And if you can’t be perfect, be consistent…
