I need to redo my again but thinking of just painting it instead. I removed mine, removed all the old adhesive... used 3M headliner glue to reattach the fabric to the shade and let it lay flat to dry for over 48 hours before reinstalling it in my truck. Within days it was sagging again and worse than before! Very frustrating...
But I like what you did here... never thought about using a t-shirt with a logo... hmmmm, now I'm thinking...
