I don't sell (or even make) candles yet, but I do sell soap & there's a definite parallel here. I believe in taking the high road and avoid making negative comments about another vendors products. When asked if my soap is 'all natural', I usually tell the customer it depends on how they define 'natural'. Then I tell them about my locally sourced ingredients, how I render my own tallow, but that I use fo's, etc. Usually, they respond by turning to their comanion and saying, "Hey Betty, did you see how pretty this soap is. And its all natural. Here, smell" Then they but some. IMO, just make a good product, be able to explain why it's good if asked, but keep away from spreading negative energy about other vendors. Let them make their own, lol. Diane W
