I came across this site called caterpillars creations who make custom made soy candles. Most candles are made from paraffin wax but all the candles made by caterpillars creations are made from 100% natural soy beans making them a much more environmentally friendly alternative. Not only are they a reusable energy source they also last three times longer than petroleum based candles and are virtually soot free.
The website has a variety of candle designs from tealights through to pillar candles and votives. Once you have selected which style of candle you want, you also have the option to fully customise your candle by selecting the colour and fragrance that you require. This is particularly useful especially when you are planning an event such as a wedding as it can be hard to find the right colour combination to match your other table decorations.
