I am trying to keep the # of threads down and may merge a few at a later date but one thing I can Recommend is the book "back to basics" I will include a scan of the contents page. Some things it is a little thin on but overall this is a "must have" book. You can find it all over the place including Amazon. It even has 2 pages on how to make your own candles.
This book was even for sale at our Hospital during a book fair last month.
