Wallpapering of window and door openings
The shape of the wall around the window determines which wallpaper is selected. In the case of a standard window, first cover the inside walls with wallpaper, trimming the paper to their width. Then hang the sheet on the outside wall like this, that it overlaps the papered interior walls, trying to match the patterns of both pieces.
Window frames in attics or attics are the most difficult to wallpaper, where we often find strange angles of inclination. For that, where the side walls are shaped like triangles, wrap around 2,5 cm of wallpaper from the main wall. Then cut the pieces of the reproducing wallpaper
the shape of the inner walls and stick them like this, to overlap that 2,5 cm belt. Wallpapering large windows, first measure and cut the sheets, which you will hang above and below the window, then the side sheets. Do not press the center sheets against the wall, until you match the patterns. Then smooth the wallpaper with a brush.
Wallpapering the door opening
Cut off full length sheets, until they overlap the door opening. Cut the sheet in the shape of an L, leaving around around 5 cm of reserve for trimming. Hang the sheet from the ceiling above the door frame and cut along the edge. Make a diagonal incision approx 2,5 cm long at the point of overlapping the angle, to be able to press the wallpaper well against the wall later. Fold the paper over the top edge and trim. Fold the paper along the side edge and trim.
Wallpapering around windows
First, wallpaper the interior walls (on the right) as described above, trimming the paper like this, to fit. Another solution is to wallpaper the exterior walls and cut off any excess wallpaper. Leave a small reserve along the vertical edge, bend and stick on the inside. Trim along the edge. Finally, wallpaper the side walls of the window recess. Make a space from the width window 6 mm, to prevent the paper from fraying.
