Wallpapering around square corner turning into bull nose corner

[cfraerg]

Hi Guys,

I hope someone can help I need to hang a patterned wallpaper around a fireplace wall . That sounds easy except the wall starts as a normal square corner but then it goes in to a round/ bullnose corner and this was very hard to line nevermind put a patterned wall paper on.

 

[He who knows]

How about a (plain) frieze strip at the height where the square corner segues into the round?
