Draw a vertical pencil line on the wall surface at your chosen starting point. Check and recheck this line using a level (Image 1). Pick up the "book" of folded paper and unfold the top section. Position it against the guide line (Image 2). When you are happy that the paper is level, brush it down from the top and crease it into the junction (Image 3). At the same time, ensure that the vertical edge of the paper is precisely aligned with the pencil guide line. Unfold the book and work your way down the wall to the floor or baseboard. Be careful not to crease or tear the paper. Keep checking that the sheet is vertical (Image 4).
Use the brush to smooth the paper over the wall and remove any bubbles. Work from the center of the paper to the edges (Image 5). At floor level, use the brush to crease the paper into the junction between the wall and baseboard (Image 6).
Brush back up the paper to ensure good adhesion. Pay particular attention to the edges and to removing air bubbles (Image 1). Trim at the top and bottom of the length using whichever method you prefer (Image 2). If you use scissors, mark the crease with a pencil line. Brush the trimmed edges tight against the ceiling and baseboard (Image 3). Use a clean, damp sponge to wipe away any excess paste from wallpaper surface (Image 4). Do the same for the ceiling and baseboard.
Make sure that the pattern is matched at eye level; this keeps any pattern drop (or misalignments) at a high or low level (Image 1). Butt the edges together tightly, checking the seam as you work your way down (Image 2). Clean the seam with a wet sponge to remove any excess paste; do not apply too much pressure as this creates a shiny seam when the paper is dry. Finish off by gently running a seam roller up and down the seam (Image 3).
When you reach a window, hang the next length of paper so that it overlaps the recess. Make horizontal cuts in the paper and bend the resulting flap into the recess (Image 1). If the paper doesn’t reach the window, it will be necessary to insert a further length. Using a utility knife, finely trim the paper so that it fits perfectly around the sill (Image 2). After cutting the ends, brush the flap into place and crease the paper into the corner (Image 3). Trim the edge so that the paper is flush with the window frame.
