If you're thinking of starting this quite fascinating hobby, then by all means, do. Don't let past failures at craft projects hold you back. Don't let a lack of "craft knowledge" place any type of doubt in your mind.
Candle making is, without a doubt, the most fun you'll ever have creating anything. By the time you've completed your first candle, your wax won't be the only thing that will be melted.
Your heart will melt as well, because you'd have fallen in love with this easy activity. But you'll also love this activity because it won't send your checking account plummeting into double digit deficits.
You can easily start your hobby on items you probably already have around the house already.
