OK, I've only done container candles for my customers and am now considering doing the clamshells. I've poured a few for testing. Now, my questions: 1. If you sell clamshells, I would assume you also need to sell the warmers, too. 2. Where are some good places to get basic warmers to sell (not seasonal, but mainly solid colors and white or off-white) Just jump on in here because I am completely open to suggestions since this is somewhat new territory for me. Thank you all for your help!
