If you want to be really Druidic,and accurate, it should be cut with a golden sickle, by the leader of the community, and caught in his/her cloak as it must not touch the ground. It should then be placed over the entrances of the house..
The reason for kissing under the Mistletoe, is another pagan practice secularised and adopted the "serial numbers filed off" and the meaning lost, it was placed at the entry to the coven or " sacred space" and that is where the High Priest and High Priestess stood to welcome the participants with a kiss... It should be taken down and burned either at 6th January or at Beltane..1st May
