Years ago, when I was still making candles from my Yaley kit , and before I used the internet for info, I innocently and naively asked the local candlemaker at the downtown market about sink holes. Proprietary information had never crossed my mind. She gave me a dirty look and mumbled something incoherent. I thought she was rude. As I got more serious about candlemaking I learned why she didn't want to tell me. I think an appropriate answer to people's questions would be: "I've spent thousands of hours and dollars to develop my products, so I'm not ready to give away what I've worked so hard for." Or, you could just say you researched it on the internet. Period, end of story. Don't feel bad. Most people don't realize that they are being offensive. I know it's annoying, but take it as a compliment instead that they want to copy your stuff! :smiley2:
