For a wand to be efficient it has to be cut in just one cut, with a brand new pruning hook, on a full moon evening. It has to be straight branches of 50 cm and if possible without any knots so that the energetic fluid is not deviated or lost. Then turn a hemp string around the largest part of it, seven times and tie it. This end of the wand should then always be the one to be held.
A few nice examples of wands.
