Hello everyone! Just started making pillars and had a basic question or two. Pic attached of a recent attempt. First - I do three pours for a pillar. The second is to fill the space created by the holes I punch, then I do a final pour to finish it off. Seems like I am getting some rough edges around the candle though. I also get that little band sometime right at the top. Do you guys recommend two or three pours? Any other advice? Oh - how important is it to use a thermometer? I dont. Fuzz...
