First, as you take down your decorations, have two boxes handy: one for those things that you no longer love and the other for those things that have lived beyond their beautiful years. Label the one of the things you no longer love so next year when you get out your decorations you can take it to the donation center of your choice. (Most won't accept holiday decorations now.) Throw the other one away.
Now, do the same for the things you are returning to your decor. Do you still love them? If not, now is the time to include them in a third box - one you can take immediately to a donation center. I can assure you everything will find a good home with someone else who will love them as you no longer do. And now you are ready to surround yourself with only those things you love!
Make your fireplace mantel a beautiful focal point. A fireplace is definitely a winter hot-spot (pun intended), so keep it beautiful even after the decorations are gone. Using natural elements will help you keep the holiday feel through the winter. Evergreens, wood, pine cones, berries are all beautiful touches that will take your mantel through until spring. Adding a bit of wool fabric in a plaid to the room (perhaps a throw or pillow) will enhance the warm, rustic look of the mantel, bringing even more coziness in.
Want something with a bit more glamour? Then try whites and metallics that mimic the frostiness of winter. This cool decorating scheme will go with most styles, giving you the freedom to stay with a neutral palette or add touches of hot colors for added spice. Try bright red, hot pink, or chartreuse. To stay with the cooler theme, soft blues and grays are a great touch. If the room feels a bit cold, use soft fabrics for warmth. A chenille throw, velvet pillows, or a knitted afghan are wonderful touches.
And if you don't have a mantel? Create one! That's easy to do with a mantel from a salvage store. (You might try ReStore, the resale outlet for Habitat for Humanity.) If it's not in great shape, a coat of paint will cover a myriad of flaws. Keep the color neutral and you can use it in any room! Decorate it just as you would a 'real' mantel and you've got an interesting focal point sure to warm any space.
Yes, un-decorating is really no fun - unless you make fun changes to bring your warmth, personality, and energy back into the space!
