If you haven’t visited a wall-covering retailer lately, you’re missing a treat. With the revived popularity of wallpaper, stores are offering an expanded range of choices. The prices of some of these may knock your socks off too.

But take heart. You don’t have to cover every wall to make a dramatic change. Papering only a single wall will do, and that’ll make some of those fine, expensive papers or fabrics affordable. It’ll also lessen the time, effort and mess of papering an entire room. This is an especially good solution for a room with plain walls, slim baseboards and window trim, and no built-ins. You create instant character.

Begin by taking a photo of your existing room and measuring its dimensions. Take these with you to the interior design or wall-covering store. Ask a specialist to help sort through options that’ll work well with your existing furnishings. The specialist will also help you pick the best wall for the new paper and estimate the amount to order.

Some papers can be hard to hang, especially fabrics, rolls with uncut edges and other designer papers. Always check the hanging instructions and ask the dealer about the difficulty level. If you’re a novice paperhanger or fall in love with a super-expensive paper, consider hiring a pro. The extra cost should be modest for a single wall, from $150 to $250.

Be sure to fill holes and smooth your wall before beginning. Rough spots might show through the paper. Then seal the wall surface with an acrylic primer. It dries hard and smooth. This allows you to slide the paper a bit more easily to tighten seams.

Cost: $122 for a double roll of the paper shown and $20 to $50 for supplies.

Time: Half to one full day, depending on the wall condition.
