She does not mention how to get eVENT.

I first heard of eVENT last year and had no luck finding any source for
the fabric. It could be a non-retail product. Some certified repair
places will sell you a bit of such fabrics "out the back door" if you
ask nicely. If they won't sell eVENT in retail, then maybe find a
certified repair outfit that repairs eVENT products.

eVENT might not have been around long enough for end-of-run sales to
show up in the specialized fabric shops.

Web search is useful in the meanwhile.
