On that section of hanging insulation, the exterior insulators that hang that stuff sometimes use a super-sized plastic flat washer when they set the screws to grab and hang two sections where they butt up to each other. Do you have a nearby perlin or rib you can use a sheet metal screw and one of those washers (or a size wide fender washer) and to secure that panel?
CK80, with all that hootch, the only thing missing is a Long Branch Saloon (Gunsmoke-Matt Dillon-james Arness- B&W TB-old) sized bar with back shelves to display it all. Any of the old school corner bars in your district coming down for renovation/ conversion into a yogurt cafe/wifi corner??
