With the three strings together, tie one knot at the top. (Tip: You can tape the knotted end to a flat work surface to keep the threads taut as you braid.) Work a basic three-strand braid so the wick is sturdy: Starting on the left side, take the green string and cross it over the white string. Cross the pink string over the green string. Cross the white string over the pink string. Cross the green string over the white string. Continue bringing the outer most string into the middle, alternating left and right sides, and you have a braid.
