So this brings my novice question. I'm a few weeks behind Jack so it'll be a bit
before I do the wings. I'm wondering about how straight these fibers need to be.
I read posts from say Andy Ellzey where I get the impression (maybe incorrectly) that
sounds like straightness is practically checked by laser :-) and then I watch
the video and it seems that all they were doing is getting the uni flat to the
surface and that their hands were certainly not blistered by the operation.

My understanding from reading is that what seems to be important is that there
not be slack in the fibers so that there are no load discontinuities. This seems
to match what they appear to do in the video. Am I misinterpreting the video
and as Andy supposes above here that they are so much better at keeping the cloth
in nice shape that they don't have much work left to do?
