Wallpapering madness

[BGD]

Hello

Are there any tips for wallpapering around obstacles, in my case I have a narrow space that includes four corners with curved coving going into the wall, so I have to paper around a range of different sized curves.

As I'm using patterned paper, I can see it going pear shaped and cursing as I try to cut it right on the fly.

Is there an easier method (like cutting it out on card maybe?)

Many thanks in advance.
