2. 3's a party...4's a crowd- When you're working with a small space, keep it simple and dial down on the furniture, there's no need to fit all your hand-me-down college furniture just because it was free. If its not in great condition or a family keepsake...donate it.
3. Not Cleaning- This shouldn't even be one of the 5, but everyone lets this one slip every once and a while. But keeping a space clean is vital to having a relaxing, calm environment. Not to mention coming up with excuses of why your place smells so bad is NOT chic or sexy.
4. Forgetting flowers- Nothing beats the aroma and allured of fresh flowers waiting on you when you return to your humble little abode.
5. Not letting the light in- This should be a mistake to avoid in any home, but this especially applies to small spaces! Like flowers, light is a mood enhancer and there is NOTHING better than drawing the curtains in the morning and letting your living space flood with natural light. Yum! Leave the curtains for nighttime privacy.
