By applying wallpaper paste (about $15 a gallon at home-improvement stores) directly to the wall, you can hang dry paper straight from the roll, saving time and ensuring less mess.
How to hang it: Starting at the left-hand side of the wall, use a roller to spread the wallpaper paste evenly on the wall for the entire length of the strip and a bit wider than the paper's width. Unroll about a foot of paper and position the top edge near the ceiling. Smooth the paper with a wallpaper brush ($3 at home-improvement stores), 10 to 12 inches at a time, as you unroll the paper.
Keep in mind: Don't paste the whole wall at once or the glue will dry and the wallpaper won't adhere.
