As those of you who I have met and welcomed me know I am new to all this, and to those of you I haven't met I hope to meet you soon. My friend that introduced me, I guess you can call her my sub, wants to play with candles specifically wax. So I'm looking for some help with proper technic, so I don't burn her, and are some candles better then others? Anything anyone can tell me to keep the play safe would be great. Thanks.
