They are also great for use in burners, electric fragrancers, radiator fragrancers and as an inexpensive way to refresh Pot Pourri. Fragrances are also excellent for those looking to create their own individual perfume blends. TOP TIP: For the most wonderful personalised scented stationery: Soak small squares of blotting paper or absorbent fabric and place in a box with some good quality writing paper or greetings cards - don't allow the scented square to touch the paper! Seal the box and leave for 3 weeks. Please be aware that these products are chemical synthetics of natural products. Therefore they have no therapeutic value - they just smell nice. Remember to dilute to at least 1% before use on the body.
