For all my outdoor projects that hang I use 1/2″ plexiglass. Anything thinner can bend so 1/2″ is the thinnest I would go. Spray a glass “frosting” product on the back or use an opaque plexi. The only problem with opaque is that the light can’t pass through the beautiful glass
The only adhesive that I found which works on all surface to surface adhesion is Weldbond and it dries totally clear and waterproof and is flexible to handle the elements.
This piece has been in our garden from 100 degrees down to 15 degrees in Oregon for 4 years now and doing great.
