I am very tempted to re-do the windsock in the future, if I can find a nice, close weave finger from a glove(silk?).Another option would be multiple coats of paint to obliterate the large weave pattern.Why am I concerned about this?Because once the dio is in its case ,the position of the windsock on top of the roof invites very close-up inspection indeed,and besides a large weave pattern like this would not be very efficient at holding any air.
Anyway,this gives you guys an idea about how I made it in cotton and a new silk one would be about the same procedure.
The brass pole will be painted in red and white barber strips for pilot visibility.
