I was curious how y'all get your pillar candles completely level. I always just did mine with a pan over boiling water and gauged it by eye, but recently I had someone order 15 from me, and after I finished I lined them up on the counter. EVERYONE was a bit different. Some slightly different in height, and some slightly leaning one way or the other. I thought about buying a small "level" at Lowes or something, but since everyone here is so helpful, I wanted to ask for opinions first.
