Here’s a vital tip - I highly recommend that you avoid making your TV wide screen & entertainment centre the focal point or it will make your room look like a temple of worship to those items. Unless, of course, it’s a specific purpose built home theatre room.
Start with your ‘big picture’ vision, Decide on your overall style or theme. Create a vision in your mind of your home in its total overview sense, as you would like to see it be & feel like.
If you’re starting from scratch, wall color paint is the quickest way you can establish your canvas, make a statement & get the home decorating ball rolling. If you’re wanting to achieve a makeover or a refresh update, changing the paint color of the rooms in your home is the most impactful & fastest way to change, & bring your room, your home to life - & also the most inexpensive. It’s like buying a fabulous new outfit, or using make up to transform your look.
