Simply place 2 teaspoons of vanilla extract into a coffee mug and place in a 300 degree oven for 1 hour. (or on stove top on simmer) Within twenty minutes the whole house smells like Heaven. It's actually a common realtor trick.
When you paint a room, put some extra paint in a baby jar* and keep it handy for quick touch-ups. don't use a baby food jar - use a peanut butter jar that has a PLASTIC lid or it will rust - shake well and use a q-tip for quick touch ups.
