First time hanging up wallpaper. The repeat is  large so I ended up with lots of scraps and had to use way more than suggested.
It can be very forgiving because after paint minor mistakes and stains can be covered. However, painting it was very time consuming because of the texture, we used a fluffy roller and still had to go in with a brush to fill it in. If you use too much paint you end up covering the detail so I guess the best way to paint it would be with an airbrush application.
I am pleased with the product and would recommend it to anyone patient enough to tackle wallpaper in general.
