One thing I dislike about winter is being cooped up for so many months with the windows shut. I don't like artifical air fresheners. Some yummy baking makes a room smell good, but then there is the downside of me consuming all those extra calories. So I do a few of these things:
#1 - Line a cookie sheet with parchment paper and "bake" citrus slices in the oven at a really low temperature for hours. The result is dried fruit which you can use as a centerpiece, but the baking time with the sweet smell is my favorite part.
#2 - Buy a squirt bottle to fill with plain old water and 20 or so drops of essential oils. Spritz in any room or on pillowcases for a room freshener.
#3 - Love your soap. Sounds ridiculous, but I love the scent of these Dr. Bonner's soaps. They're pure and come in scents like peppermint, almond, lavender and eucalyptus. I fill the sink with some water and a few drops of this soap and leave it in the sink once I'm done my housecleaning. The scent remains for hours.
#4 - Throw a branch on the fire. We live in an old treed area, so there are often broken pine branches on the ground at the park that we can scoop up. I like the crackle and scent of one on top of our fire logs.
What smell good tricks do you use?
