Unscrew the wooden top and remove the plastic stopper. Put the wooden top back on and flip the bottle upside down to get just a bit of the oil onto the wooden top. Do not over saturate the wood as you don't want the oil to seep up the string. Take the wooden top back off and put the plastic stopper back in. By putting the stopper back, you stop the oil in the bottle from evaporating and stop accidental spills. Put the wooden top back on, hang and enjoy!
