Use new throw pillows and blankets
Another easy way to give your bedroom a seasonal look is by switching up the color of your throw pillows and blankets. Many retail stores sell inexpensive throw pillows that you can put out during different seasons. Doing this isn't permanent like painting your walls, and it lets you add seasonal colors quickly.
In the fall, we recommend using throw pillows and blankets with warm colors. In the spring and summer, you should use light, lively colors. In the colder months, grays work well. You can even use a holiday-themed throw pillow!
