wingsail cover plan for tiki 26?

[kim whitmyre]

I have a headsail bag coming, but right now I am simply using a tarp to wrap over the wingsail. . .I'm in the planning stages for a custom cover for the wingsail: any tips, ideas for making it easy to use? I've heard no velcro (gets dirty and won't stick), but good things about the twist-lock fasteners.
