It's easy to create your own air fresheners in your favorite scents for a fraction of the cost. Here's how:
You'll need essential oils (find these online at Amazon or at your local craft store) in the fragrance of your choosing, 2 cups of water, 4 packets of unflavored gelatin, and 2 tablespoons of salt. You will also need empty candle containers and food coloring if you want to tint your candle.
To make these, simply add the food coloring and oil to 1 1/2 cups of water and add heat. Add the salt and gelatin. Remove from heat once the gelatin is dissolved.
Add the remaining 1/2 cup of water (cold) to the heated mixture, stir, and put into containers. Let them sit for two days.
