VIRTUOSOFil Invisible Vectra Steve Fearson - Magic Wire Levitation Thread, Black, Compatible with Human Hand

Vectra Virtuoso - Expert Grade Invisible Thread  I was really pleased when I received this thread. It is strong enough to hold up a deck of cards without breaking. However, it is slightly shiny which means it might be unsuitable in some environments. This can be overcome by standard work with markers etc. Overall, worth a purchase, if only to see whether it will work for you. (As with all thread, light from the front)
