I am contemplating making a small boat sail out of a piece of Tyvek
housewrap I have on hand. The material I have is not the tough random
fibre Tyvek of postal envelope fame, but what appears to be a lower grade
woven pattern in two laminates which can be separated easily. I can find
information online about how to make Tyvek sails but no follow up on how
the sails perform or on how long they last. I'd like to hear, if
avialable, comments on ...

- how long Tyvek lasts as a sail

- if Tyvek sails perform differently, stretch and so forth. I plan to cut
the edges to give the sail some shape, using the usual measurements, and
wonder if that's applicable to Tyvek. (I've used the sprit sail info I
gathered over the years and put in the file under Boats on my website).

- how well the double-sided carpet tape holds and lasts

- if it would be better, or even possbile, to use a sewing machine

- if the printing can be removed

- anything special about folding and storing when not in use

and any other helpful info
