Is the drab decor of your bedroom keeping you awake at night? The following ideas are quick, easy, and affordable ways to spice up your bedroom decor and give you relaxation and good rest.HeadboardConsider changing up the headboard on your bed by giving it a paint job or even covering it with stylish fabric. No headboard? Create the look of one by painting a rectangular block above your bed. Experiment with different headboard shapes to find the perfect one that will bring your bed to center stage.LightingEspecially if you are an apartment dweller, your bedroom lighting may not fit the bill of relaxation and romance. Adding some lanterns and making them a focus area of your bedroom is sure to do the trick. Check out maru round white paper lanterns(World Market, $4.99-$6.99) for casual simplicity. Another great option is the large voyage punched metal lantern(World Market, $24.99) for a worldly, exotic look.Window Of OpportunityConsider switching out a drab window treatment. You could even make your own with beautiful sheets or inexpensive designer fabric, as buying manufactured ones can be costly. Making your own is as simple as measuring the fabric you need and making a hem wide enough for your curtain rod to slide through. If you do not own a sewing machine, consider buying no sew tape(Amazon, $4.12) that will solve your problem in minutes.Stylish ShamsA budget friendly way to give your bedroom an update in minutes is by changing the shams on your pillows. Try room essentials leaf shams(Target, $9.49) for a nature inspired look.Fashionable FurnitureIf your bedroom set is keeping you in the past, overhaul it with a can of paint. Choose a neutral color for a subdued, natural vibe, or go bright and colorful to bring a splash of style into your bedroom. Replacing hardware is a quick way to update your bedroom furniture while you are at it, and it is also fairly inexpensive. Look for hardware that will introduce charm, such as rosy knobs(Anthropologie, $6.00-$8.00).Stencil ArtStencils have come a long way, from ultra kitschy to modern and fabulous. Check out Lotta Jansdotter Stencils(Amazon, $11.94) for stencils you can use on your bedroom walls, ceiling, furniture, or textiles. If you want to skip on buying stencils, create your own using thin cardboard and a utility knife to cut out a simple design.Designing With DuvetsAs your bed is the largest item in your bedroom, covering it with outdated textiles is sure to ruin the relaxation factor. Switch it up by purchasing a new duvet that suits your style. Consider the dwell studio crosshatch duvet set(Target, $17.48 to $41.98) for feminine flare or the room essentials striped duvet set(Target, $19.99-$34.99) for simplicity in stripes.
