Once you have hung wallpaper, and creased it properly on the first side of your doorway, you are ready to move on and finish the job. Don’t get sloppy now, or all your hard work will be a waste, and remember that while this task may seam tedious, doing it correctly is the only way to ensure your new wallpaper is really shown off.
Step 1 – Shorter Pieces
Depending on the width of your door and your paper, you may very well have to hang a piece of paper between the two corner pieces. This is a much simpler task, requiring you to use a shorter piece of wallpaper, and hang it at the top as you normally would. Smooth it downwards, carefully along the seam, and when you reach the doorway, smooth in a crease just as you did before, making sure to fold over the excess to prevent it from weighing the paper down before you can cut it.
Step 2 – Repeat a Step
Hanging your paper around the other side of the door is the same process as with the first. Cut away a rough corner, cut a diagonal with scissors, tightly into the corner of the doorway, then crease the paper in and then fold it.
Step 4 – Cutting the Excess
Before you are ready to cut corners, use your scissors to cut away some of the excess paper, leaving an overlap only as thick as the trim it runs along. This will allow you better visibility and control when you’re ready to make the final cuts.
Step 5 – Cut Along the Casing
Starting at the top corner, find where the casing meets the wall and carefully work in your scoring knife. Using this thin gap as a guide, cut away the last of the excess paper where it is creased into the door frame. Make sure your blade is sharp and clean, and run it slowly down the doorway, from top to bottom, making a clean straight cut. Repeat this on the opposite side and then climb up a ladder to carefully make the cut along the top. Be extra cautious cutting along the top that your blade doesn’t get caught on any of the seams, and damage the paper.
Step 6 – Smooth the Transition
Use your paper hanging brush to smooth the wallpaper around the doorway. Clean off any excess paste on the trim with a wet sponge, and make sure all your seams are straight. Then finish up that room.
This timely but simple process can be repeated for both closets and windows as well. Once you have it down, you will find it much easier to do the next time, and perhaps you will find the entire task of wallpapering a room much less daunting. As with any DIY project, the results depend entirely on you.
