While I am of technical mind, here is a hypothetical hint I want to throw out here and see what you all think.
I'm covering Oly's Wylie (inside joke to the Coyote). We are having some humid weather. I've chased wrinkles twice on every part so far. I'm not trying to avoid doing the last detailed shrink but I am afraid the wood will move a little when it get's there. I'm thinking it best to get all of the seams done and doing a quick onceover but it may be better to let him tighten everything once he gets it and she settles down.
