I am about to wallpaper a room. I've papered rectangular rooms with four walls before and done all right but this time I have got to tackle an external corner. What's the correct way to do this?
If I take the roll and wrap it around the corner, if the wall isn't completely true then won't the roll then be at an angle?
If I tackle it as I would an internal corner and take the roll around the corner just a centimetre or so and then paper over the overlap, wouldn't this leave an ugly join on display?
Which brings me to my second question: what is the correct way to do window reveals? In a way these are small scale external corners. I usually try to fold the roll around the corner and into the reveal but you can only fold it one way: either into the side of the window or into the top. Whichever one is left has a visible join.
When (or if) you fit curtains I suppose this would hide a vertical join, so is it best to fold into the top of the reveal and have the join along the side?
