Your only option, rational option I mean, is to call her and tell her that since you do not usually use that size jar you need another week to test. Then, You will have to pour three testers at a time of each scent she bought(3 different wicks), burn them, pick the best of the three, pour two more testers of that one with the same size wick, and then test them to make sure your wicking is right...then pour her candles. You have time to do it in a week, but you will have to keep good notes and stay on top of it daily. I don't know the diameter of that jar, so we need that to give you wicking suggestions. You honestly should have turned down that order or asked for a month. If someone asks me to do a special jar size or scent, I always ask for a month to test, and I have been making candles for a LONG time, so have a pretty good idea where to start. You don't screw around with candles...you need to test thoroughly, and if you haven't, you shouldn't sell them. JMO>
