Good to know...I'll have to try some cotton. Can I just go to Walmart and get some white unbleached cotton yarn then boil it to prep it?
Sure! I just picked up some "all purpose dressing" gauze at Walgreens this morning, 100% cotton, very loose. It should be easier to roll into a wick than un-braiding the candle wick that I have now.
But, if you have a length of silica wick, try un braiding it into thinner strands, then bundling it back together, then wrap your coil around it.
