I think many people made, tested and then tested again for a long time before even thinking of selling their product. I don't do candles but have been playing with it for over a year. I do soap and other B&B and have been doing so for 7 years I tested and researched for well over a year before even considering selling. I had family and friends as guinea pigs. I also didn't sell anything until I had insurance and all my other ducks in a row (tax stuff, sales tax, business registration etc). Others may have a different perspective. But I didn't want to risk everything if something went wrong. Unfortunately, we have no control on how others will use our products.
