How to Trim and Cut Wallpaper: Tools, Approach, and Tips
Dry wallpaper is naturally stiffer, and easier to cut with scissors or a -blade knife. The reason is that dry wallpaper has more resistance to the sharpened edge of the blade, which allows the cut to be smooth and straight. If you have ever cut brown wrapping paper with a pair of scissors you may recall that once you started the cut, you could push the scissors straight across the paper without opening the blades any further. Most dry wallpaper will respond in a similar fashion.
