I second plungerman's response. I have been doing Eugene's method for a good many years. I hook-up in from of them and un-hook in front of them. I always wear black and the B***K T****D does not show against what I'm wearing. Simple and easy.

But what about people from the side? Or do you only use it in formal performances with people sat in front?

I have never had any problems with people being at my side. The B***K T****D runs from a button on my vest along my arm to the cards. No one ever sees it.

I think Paul may not understand. With the proper handling you can bring out the guilty card in front of them, set the B***K T****d in front of them and proceed with the trick. It takes so little to set and the parts are invisible.

I had a killer floating card once, (Eugene said so), but it had more invisible t****d than David C*****ield going. People would have to be led into the room to see it, then led right out.

invisible t****d is fine but if it works, go ahead and use rope.
