I used the 8% because that is what I use in my soy even though others use less. Do you think that little bit could effect things? I didn't notice the candle was tilted , I do level them off. I am at work now but will check when I get home. Maybe it was sitting on a mess that was on my tray. I lit them and them in a row for the photo and then moved them to their burning spots. I have not abandoned it yet so Thanks and I will check it out .
