Guide
A good hang is mostly preparation. The wall you start with decides how the finished room looks far more than the pattern does.
Prep the wall the pros do not skip
Wallcovering telegraphs every flaw underneath it. Fill dents, sand ridges, and skim any patched drywall smooth, because a raised seam or a lump reads clearly through paper once light rakes across it. Wipe off grease and dust, then prime with a wallcovering primer, not flat wall paint.
Primer does two jobs: it seals porous drywall so paste does not soak in and dry out, and it gives a slick surface that lets you slide each strip into position before it grabs. Skipping primer is the single most common reason a first hang goes badly and the single hardest thing to fix afterward.
Pattern match and the seam plan
Before cutting, decide where the eye lands first and hang your first strip there, plumb to a level line rather than to the corner, which is almost never straight. Work outward in both directions so the least-perfect seam ends up in a low-visibility corner.
Straight-across and half-drop are the two common match types. A half-drop stair-steps the pattern, so every other strip starts halfway down the repeat, which means more planning and a little more waste. Read the match type on the roll before you cut a single length.
Living with it and taking it down
For daily care, dust naturals with a soft brush and wipe vinyls with a damp cloth; never soak a seam. Keep a leftover roll from the same batch flat and dry so a future patch matches.
When it is time to remove, nonwoven strips off dry in whole sheets. Older pasted paper usually needs a scoring tool and warm water or a steamer to release the adhesive. Knowing which you have before you buy saves an afternoon of scraping later.
