Great for decorating kids' rooms or any room that needs a lift, decorative wall decals create flexible designs for little effort or expense.

Removable vinyl wall decals stick on to most walls and offer a quick and easy way to decorate a room without the mess and cost of wallpaper and paint or stencils. Wall decals are designed to remain in place for an indefinite time, but they also peel off when you need a change of scenery. Some self-adhesive wall decals are reusable and repositionable, but many are not. Choose the location for your decals carefully and make sure the surface is clean of oil, dirt, and dust before you apply your decorative art.

A whole host of online retailers, both large and small, sell wall decals online. Following is a selection of shops that offer wall art stickers in designs ranging from dinosaurs and sports to abstract and whimsical.

Blik Surface Graphics

With a selection of wall graphics that include space invaders and Keith Haring art, no site beats blik for creativity and selection of matte vinyl wall decals. Decal designs include friendly dinosaurs (pictured below), bamboo stalks, modern dots, and trompe l’oeil bookshelves, all designed to spice up a blank wall. The blik site also includes a step-by-step “how-to” section for applying the decals, which are removable but not reusable.

For “bliks” you can reposition, choose from the Re-stik line of blik products. Pricing and shipping varies. Some stores, such as Urban Outfitters in the U.S. and Home Depot in Canada, sell blik decals in their bricks-and-mortar locations. Sample price: the 31-decal Re-stik dinosaur package is $38. Shipping varies with UPS.

Chalkboard Repositionable Decals

Create an instant chalkboard or an erasable artist’s canvas with chalkboard wall decals from Brightandbold.com. The chalkboard decals come in basic rectangular shapes, bubble quote designs (seen below), and in the shapes of a house, trees, and flowers. The vinyl decals can be removed and reused without damaging paint, according to the manufacturer. For fun, place a bubble quote decal next to a portrait of Great Aunt Gertrude and let your family take turns imagining her comments. Price for a set of five bubble quotes in two sizes, in blueberry and grape colors: $19.95 or two for $37.95. Free shipping.

Put Your Mug on the Wall

Got a snapshot you really love? Blow it up as large as 7 feet high and stick it to your wall through an online service such as Wall-Graphics.com. This site allows users to upload a digital photo (shot with a camera that has 3-megapixel resolution or higher) and choose a size from 24 inches on the shortest side ($24.99) to 84 inches on the longest side ($99.99). The company will cut out the subject from the background (see sample below) and send you a life-size or bigger photo decal that sticks to any flat wall and can be moved and reused.

Personalized Wall Decal

Elephannie’s etsy shop sells personalized vinyl decals that match a mermaid or shark with a name of your choice. Choose from one color or two in matte (white, red, brown, dark pink, violet, turquoise apple green or black) or metallic (copper, silver or gold). The vinyl stickers are removable, but not reusable, and may cause minor damage to painted surfaces, warns the artist. Price: $12, free shipping.
