Ed If your going to use a fantasio, use a streamer, or ribbon rather than a full square silk, because it will fit better.
I have to say though as an opening effect for stage or caberet, Id be inclined to enter with a cane, which i would use as a pointer.
I would have a a coloured silk" freely" chosen, then presto. your cane changes into the "freely" chosen coloured silk.
I would then explain that what the audience has just seen, is a magic trick.
And i would continue the show demonstrating the difference between that one piece of " magic" and mentalism.
