You can change the string on your flow-wands to suit your style of play. This video shows how to string a short-string wand - a long string is even easier as you do not need a finger loop.
A note on string material: The black string is chosen for its strength and durability - invisible magician's thread is too weak and will break with active use. We tried using white, silver, and grey string and fishing line, and surprisingly they are more visible than black as they catch and reflect light. The wand is not designed specifically for magic, but rather for movement. The magic is in your movement :)
