Homemade Fabric Softener (My clothes are SO soft - softer than with store-bought, and smell fresh and clean. The scent of the conditioner is definitely there. This recipe makes a lot of softener, so I only made half.)
Put two caps full of vanilla extract in a coffee cup, then place it in the oven at 300 degrees for one hour. Within twenty minutes the whole house smells like Heaven. Its actually a common realtor trick.
