How to Cover Windows Without Curtains
If you're not a fan of curtains, there are plenty of other ways you can cover your windows. Install blinds on your windows for a clean look that's fully adjustable to the amount of light and privacy you want. For a cheaper option, get fabric shades, which allow more ambient light than blinds when they're closed. You can also install shutters, which give you partial visibility and a more rustic look compared to blinds. For a quick, temporary solution, hammer 2 nails into the wall above each corner of the window, tie string between the nails, and hang a sheet of fabric over the window. Alternatively, block the window with houseplants or other large objects for privacy.
Place a sign or screen in front of the window for a temporary option. One of the fastest ways to cover your window is simply to prop something in front of it. You can use pretty much anything, from a sign or artwork to a privacy screen for larger windows. It's easy to change this out when you want a new look. In addition, you don't have to worry about putting any holes in the wall if you're renting. If your style is farmhouse-chic, prop up a pretty hand-painted sign with a cheery message like "There's no place like home." To cover a large bay window or sliding doors, try using a folding room divider that matches the rest of your decor. Put colorful glass bottles in the windowsill for a pretty display. A collection of glass bottles will catch the light beautifully. It will also help provide some privacy since anyone looking in will see the colorful glass, rather than the inside of your home. Search secondhand shops for cool glass pieces in a variety of shapes and sizes, or repurpose bottles you might already have on hand. For a sleek look, stick to 1 or 2 colors for the bottles in your window. If your style is more eclectic, pick an array of bright shades. If you can't find any colorful bottles, try painting some yourself ! Mount a shelf in front of a window for partial coverage. A shelf is a great way to partially cover a window without blocking out natural light. Measure the width of your window, and buy a shelf that's about 4 inches (10 cm) wider at a local home-improvement store. Mount the shelf as directed in the instructions that come with the shelf. Then, decorate the shelf however you'd like. For instance, you might fill the shelf with a houseplant, a couple of books, and a decorative vase. Try using glass shelves to make the most of the natural lighting. As an added bonus, you'll get a little extra storage space! Hang a DIY valence made of draped fabric in front of the window. Drive 2 nails or push pins into the wall, 1 on either side of the top of your window. Tie a piece of twine or string between the nails, then hang 15–20 pieces of fabric over it. Each strip should be between 20–25 inches (51–64 cm) long. Use bandanas, scarves, or a leftover fabric garland. The valence will fully cover the top portion of your window but still allow some visibility and natural light. For a more refined-looking valence, hang a curtain rod over your window, and drape pieces of fabric over the rod. Place 3–5 tall potted plants in front of a window. While plants aren't technically a window covering, they're effective at partially blocking visibility while allowing in natural light. Try setting a few leafy houseplants on the windowsill of a kitchen window, for instance. Or, if you want to cover a tall, narrow window, like in a hall or entryway, set a single tall houseplant directly in front of it. For a low-maintenance option, use artificial plants, birch or willow branches, or dried pampas grass. Attach faux stained glass to your windows for a colorful look. If you'd like to cover your windows while adding a burst of color to your home, faux stained glass is the way to go. Purchase pre-made faux stained glass windows at a hobby or craft-supply store. Depending on the window's location, either lean the faux stained glass up against it or attach the glass to the window frame with mirror hanging hardware. You can also make your own faux stained glass panes. Just paint the pane a variety of pretty colors with stencils and glass paint. Layer gallery glass over your windows to create an opaque surface. If you want to make the surface of your windows translucent but don't want to completely block visibility and natural light, try gallery glass. Gallery glass is a liquid that you can apply directly to your windows that dries opaque but still lets in some natural light. If you want your window to have a textured look, run a toothpick through the gallery glass before it dries. To create a border on your window, or to define shapes on the glass, trace the outline with liquid leading first, then apply the gallery glass after the leading has dried. Purchase gallery glass and liquid leading at a local art-supply store or hobby shop. Apply window insulation film to the windows to keep in warm air. Window insulation film adds an insulating layer over your windows and will trap warm air in your home during chilly winter months. To apply it, stick the adhesive side of the insulation film directly onto the surface of the window. Then, blow hot air onto the film using a hair dryer. After 3-5 minutes, the film will shrink and fully adhere to the window. Many of these films are transparent, so be sure you choose a tinted film if you want the extra privacy. Purchase window insulation film at a local hardware store or any major home-improvement store. The package should clearly state how much glass the insulation film will cover. Etch the glass for a frosted look. Pick up some glass etching cream and an artist's paintbrush from your local craft store, along with a stencil, if you'd like to use one. Clean the glass thoroughly and let it dry, then brush the etching cream onto the window and let it sit according to the directions. Then, rinse away the cream with a sponge and clean water. When you're finished, the window will have an opaque, frosted look—so you'll have all the privacy you need, with no curtains required! Be sure to wear gloves, since the etching cream can irritate your skin. Keep in mind that this effect is permanent, so if you're renting, you may need to ask your landlord's permission to do this. Install vinyl blinds for a clean, simple look. Blinds are a great substitute for curtains. If you'd like to try blinds, you'll first need to measure the width and height of your window. Then, purchase sets of blinds at a local home-improvement store. Begin the installation by hanging the brackets at the top corners of each window. Then, hang the head rail and attach the valence over it once the rail is in place. Basic horizontal vinyl blinds are a great option if you're shopping on a budget. However, there are more sophisticated options if you want to spend a little more! Blinds are a great option to cover your windows when you still want plenty of natural light. Just open them in the morning, then close them at night for more privacy. Choose wood blinds for your office, den, or study. Wood blinds are perfect if you love a warm, rustic look. They come in a variety of stained or painted colors, so it's easy to customize them to suit your décor. As with other types of blinds, they can be adjusted throughout the day when you want more light—or more privacy. Do not install wooden blinds in the kitchen or bathroom, since the moisture could damage the wood. Opt for vertical blinds in a window that’s wider than it is tall. Vertical blinds work well in tall, narrow hallway or entranceway windows that are less than 1 foot (30 cm) wide. They cannot be raised and lowered, since the slats are vertical. However, you can still adjust the slats to let in more or less light depending on the time of day. Installing traditional horizontal blinds in a tall, narrow window would be impractical and look odd. Use shades for a soft covering that allows ambient light. If you don't want your window coverings to block out too much ambient light, choose shades. Shades are typically made of soft cloth and can be raised or lowered during the day or night, respectively. They also allow more ambient light than blinds and come in a larger variety of styles. Purchase shades at any home-improvement store. Install honeycomb shades if you live in a cold climate. Honeycomb shades contain many small tubes of air that hold warm air to help keep your home warm overnight. Try woven wood shades in rooms that receive overly bright sunlight. Woven shades are typically made from bamboo. They block a great deal of light, but can still be raised and lowered depending on how bright the room needs to be. Select Roman shades in more formal dining or living rooms. Roman shades are made of billowy fabric that you can raise or lower to let in more or less light, or to block the inside of your home from view at night. They're considered a sleek option and are typically custom-ordered for individual windows. Also order blackout Roman shades if you'd like the option to shut out all light from a room. If you like the idea of fabric shades but don't have a formal room, choose a shade made of tightly woven opaque twill. Mount panel shutters over your windows to block visibility at night. Shutters are a common alternative to curtains and blinds. The horizontal slats allow partial visibility, and you can open or close the shutters depending on the time of day and intensity of the natural outdoor light. Purchase shutters at your local home-improvement store. They come in a variety of colors, sizes, and materials, so choose an option that suits the size of your windows. The shutters will come with directions for how to install them. If you'd rather not install the shutters yourself, the home-improvement store can send professionals to install them for you. Install interior barn door shutters for a rustic look. Indoor barn door shutters are practical, but they also have a gorgeous aesthetic. They give your home a rustic, rural appeal and, like traditional shutters, can be adjusted to let in more or less light throughout the day. Most styles of barn door shutters slide back and forth on track mounts. Purchase barn door shutters at a home-improvement store near you. Many large online retailers and general home-supply stores also sell barn door shutters, although these may be a lower quality. Set up plantation shutters for full control over the visibility. Unlike panel shutters, plantation shutters can be minutely adjusted from inside of the house by raising or lowering a bar that controls the shutter slats. This allows you to make slight adjustments to the amount of natural light that enters your home as the position of the sun changes. Plantation shutters also fully reduce visibility in at night. Buy plantation shutters at any major home-improvement store. As with other shutter types, you can either install them yourself or ask the store to send a technician to install the shutters for you.
