Wall coverings can have the biggest impact in a room's décor scheme, both in terms of design and, if you're not careful, your wallet. Fortunately, affordable new technologies and turnkey products are making it easier than ever to achieve professional, predictable results on a do-it-yourself cheap budget. Here are some popular and affordable options to consider for your wall-to-wall redo.

Your wall is your palette.  Paint is one of the most affordable wall coverings of all, but make a wrong move with your color choice, and you can easily end up paying and working double to correct the offending hue. For great results the first time around, major paint brands have rolled out several tools that let you try before you buy, including on-line room visualizers, pre-coordinated color palettes, and, best of all, trial-size paint samples. Ranging anywhere from two to eight ounces in volume, these allow you to paint a generous area of color on a piece of scrap board or directly on the wall to literally see it in a different light. Various times of day reveal various combinations of direct sunlight, indirect sunlight and artificial light that can transform a color (or at least your perception of it), and large-scale swatches are the best way to ensure you'll enjoy living with your selection around the clock.

Choose from cheap pre-pasted and easy-change varieties, go for texture, and complement with borders and other embellishments. And remember those full-wall murals? They're back in vogue again, and thanks to digital technologies, photographic vistas are all the more alluring and trompe l'oeil illustrations have the look of personally commissioned artwork. Just as with paint, it's easy to test your wallpaper design plan with large-scale product samples and visualizers, and illustrated step-by-step application instructions are only a click away.

On board for texture and architectural interest.  Another great and affordable wall covering is wallboard, now available in a range of textures and patterns for floor-to-ceiling fashion. Far from the shallow-grain wood paneling of yore, today's options include stone and tile looks, leather, metal, and bead-board styles. High-moisture environments meet their match with special compositions like cellular PVC, and wood-look varieties can be painted or left as is depending on your color preference. Design with a wainscot or full-height scheme in mind, and install it all with just a few traditional tools. Your cheap wall covering scheme can also include specialty panels such as chalkboard or marker board for planning future projects.
