Using candles around the home: Candles have a memory so to ensure that you get the most economical result from them, trim the wick to 2mm before each use. With wood wicks, be sure to remove any wick trimmings from the candle surface prior to lighting. Burn candles in jars for at least 3-4 hours at a time. This ensures that the wax liquefies across the surface of the jar and burns evenly.
Electrical cords: Save the plastic tags from loaves of supermarket bread and attach them to the cord next to the plug of each electrical item in your office or living room. Then label them accordingly: TV, Monitor, Printer, DVD player etc. This way you can see at a glance which plug cord is attached to which device.
