I use peaches and cream cotton yarn from walmart
3 strands in a coil wrapped on 1/16 in drill bit with 7 wraps of 32ga gives me 2.1 on a V5 Vamo
Lay it on the ledge then asemble dont block the chanels
The wick I have in now is 5 days old and flavor still great
Ive been running this experiment to see how long the wick lasts before the flavor goes bad
so far so good
