I don't sell candles, so I can't comment on that aspect, but I do make candles for my own family's use. I have several different silicon Lyson molds, and I'm very happy with all of them. I just recently got Lyson's votive-sized skep mold, and it's very cute. I can see why they would be popular with people at farmer's markets and the like. I also have a birthday candle mold that I purchased on Etsy. The most difficult part about candles is finding the right sized wick for the various shapes and sizes of candle. I'm still experimenting with several of my molds. I get all my wicking from Waxing Moonshine, also on Etsy. They have great prices, quality, and customer service.
