Back to the wing sheeting. After it sat for a few days I took it out of the robe and trimmed it to length. It was certainly saturated.
After the starboard wing repair I had decided to try a different method that wouldn't require a joint at the leading edge. So I marked a centre line on the wing and the sheeting...
... pinned it in place...
... and placed magazines to shape it.
I'll leave that for a couple of days.
