Be careful using colors that are too dark, or too strong – you should tread carefully with dark browns, dark reds & dark greens – they can overpower a room & make it seem daunting, uncomfortable, unrelaxing & even claustrophobic.
Are there any home decorating styles that you like, or that you tend to gravitate towards that can give you a general direction? Perhaps its Country or Rustic, Mediterranean or Tuscan, Asian, Classical, Contemporary, or a combination of some? Which do you or would you feel most comfortable in every day?
Or, if you feel drawn to start with another room, perhaps your sun room or child’s room, then follow your instincts & preference. It’s important that you don’t feel overwhelmed. Start small if you feel more comfortable. Feeling overwhelmed will most likely block you & you won’t move forward.
