1. Keep it Cozy
Staying warm in the winter doesn't mean spending lots of money on heat. Blankets, cozy hoodies, and slippers go a long way. You can also regulate the heat for when you are actually home to save money and keep you comfortable. You might want to get your hands on a Nest. And don't forget to reverse your ceiling fans!
2. Use Warm Fabrics, Soft Lighting
With winter coming, it's time to pull out the flannel, fleece, fur and fuzzy fabrics. Dark, earthy tones will be your friends, as will lamps with low lighting. These fabrics can be worn, used on furniture, over windows, and under your feet.
3. Make Awesome, Winter Foods
Nothing is better in the winter than a large bowl of soup, a cup of tea, and getting cozy in front of a fireplace. Chicken pot pies, hearty stews, tea, and other such foods will make you forget the temperature outside, and help you focus on the warmth inside.
