What adheres to Leahter

After seeing the Mailbox (still don't know if its leather work) I decided to post this. Liquid Nails is a great product for adhesive work. After researching what to use to glue Mirrors to leather. I found Liquid Nails Mirror to work. Not only does it hold strong but when it dries it maintains the metallic properties needed to have glass be a mirror. If you've noticed the black spotting on mirrors that can be the problem without an adhesive compatible to this work. And yes the saddle is leather with a fiberglass tree. 20 inches long and 22 inches from horn to stirrup. After I finished it I sold it to a local Saloon. Where I can enjoy it with a nice beverage!!
