Thanks for all your info. I have decided to invest in a dehumidifier
for the shop, just in case!

I looked at the RH/moisture content charts and decided it should not
be a problem. By the time the piece goes in, spring will be around the
corner and the RH of the house will be on the rise - the cherry won't
feel the effect much if at all.

Another insurance against problems: I bought quartersawn cherry for
the door panels, drawer fronts and countertop. Should look pretty
nice!
