I sanded the walls first to give it a bit of a key and am using general wallpaper paste. DISCLAIMER: DO NOT COPY THIS METHOD as there is more to the story. Some parts of the curved front are tricky so I am making cuts in the paper where necessary to help shape it. There are some crinkles forming in it which is a worry but we can’t stop grinning at its loveliness. I have also papered the stable doors and the inside of the hatch I’ve done upside down so people/customers hopefully, can read it while they are waiting for food. When it is all shut it looks a bit mental though and I keep doing a double take and then doubting myself.
