Need your advice for a project

That shutter thing looks like a metal windshield sunshade. Wonder if you could attach foil to a flat, cardboard sunshade, then compress the accordion/sunshade to the desired size?

Also, I remember from years ago hard candy on string. Dip the string, let cool, repeat until desired diameter is reached. Kinda like rubber-coating the handle of a tool...
