Hello everyone, My name is Jenetta and I am new to candle making. I'm am having the same issue as well, where my candles are extending out, but having some wax left on the sides. I am using 8 and 10 oz jars and using Eco size 8 wicks. I have not tried any other wicks. So I'm understanding from you all that hang up wax on the sides of the jars are normally and the wax will start to come down, after a couple of burns. That is very helpful information. Also, do any of you guys use eco wicks? If so, how do they work for anyone that use them. I am using Natural 464 wax.
