I contemplated the local sailmaker.
Alas, they don't exist. Local anywise.
I am fairly landlocked here.
But bundling it up and mailing it away to be copied is a possibility.

The existing one lashes to the pole with grommets. These grommets are pulling out of the weakened fabric. I am wondering about other solutions. Ie, a sleeve over the pole like a laser sail, or webbing straps sewn on.
