3. Too Many Knickknacks Knickknacks, decorations, tchotchkes, accessories, call them what you want, but we all have too many of them. Rotate what you have, and if you really like something but it’s been out for a while, store it for a bit. You don’t have to have it all out at once and every surface should not be covered. Edit your collections so they’re pointed and look good as a small grouping.

2. Pillow Overload If the pillows actually hinder being able to sit on a couch or lie comfortably on a bed, then it’s obviously too much. Instead of buying so many pillows, spend your time, energy and money decorating an area of the room you’re actually looking at when sitting in bed.

1. Fake Flowers This is a controversial topic, but fake flowers (and plants) are a mistake. They gather dust and don’t bring life into your home like real flowers, which look and smell better. Fresh flowers are expensive, but there are other things you can do instead of buying them all the time. Put lemons or other fruit in a bowl for a punch of color. Or, use some dried natural material like curly willow or bamboo stalks for a fresh look.
