For the Unabridged Wonder line of candles, the Premier 700-series is our preferred wick. Our distributor, Black Tie Barn, has this to say about them: 

“...[they] are a flat braid cotton core wick made from textile-grade cotton. They are designed to promote clean burning and minimize mushrooming from carbon buildup. Premier 700 Series wicks can be used in tealight, votive, pillar, and container candles. Their versatility makes them suitable for both paraffin and soy waxes.”

I have found them to work very well in the more viscous coconut/soy wax used in these candles. Like any wick, they do need to be trimmed every so often, but I’ve found for most of the scents, they don’t need to be trimmed after every burn, but every other burn or so.
