She wants a scent you don't already have? Does she know you don't have a "true" cherry? I would bring her the cherries you do have and let her pick one. Explain to her the time expense involved in testing a new FO. If you do have the time to do the test, then charge a $20 set up fee for finding and testing the new FO. Also, I would not let her smell OOB. The FO can change in the wax and then she might not be happy with the candles. Be assertive. YOU are the candle expert not her. YOU CAN DO THIS. and YES get a contract - ESCPECIALLY between family and friends. And if you get your costs covered in that deposit, if things go sour you are not out the money to buy the supplies. JMO - I have been burned by friends several times. WILL NOT happen to me again. Hope it doesn't happen to you either. Dat
