Palm wax is great, but takes a lot of hit and misses. I have used all kinds of wicks and most of them work fine. The problem I have is keeping the wicks straight (when using spooled htp, cotton ect.) and avoiding leaks. Tried everything from plugs, screws, tape, sticky stuff. If your wick is not straight, your candle wax will not melt straight down, and cause a mess. I have finally found a solution. Wick pins are wonderful. And I use primed rrd40 wicks. Works great. Candles burn straight down (most of them, remember there are lemom candles too, nothings perfect). Hope this helps.
