Help with sitting? Am having unusual issues.

[ThistleDown]

I really thing you are over-worrying this thing. I don't do anything other than those who have posted to your thread (except for the bungiecord one -- phew!). I simply 'sweep' the pleats from the rise to their end -- and sit. Perhaps that needs a demonstration video or videos? I'm sure that XMarks could come up with those and I'm a tad surprised that we haven't done so already. I guess we'll have to get on it
