My guess is that you are too conscious about your TT when you have it on, or you're using a bad TT technique which people can catch. Being conscious and uneasy about using a TT, you tend to "show" your uneasiness to your audience without you realising. You might have glanced at your TT during your performance. Remember, people will look where YOU look. They'll follow your eyes.
More practice. Learn/develop good TT handling techniques (Darwin's DVDs, Patrick Page's DVD, Salvano's DVD etc).
I stand by these rules:
Rule #1: TT should never even be seen
by the Audience. This means you DO NOT even flash it. Its hidden from view the whole time
- Applicable if you're wearing a neon yellow TT. Not as convicing as.......
Rule #1.5: If using a skin-color TT which all of us do, Flash it for NO more than 1 second
. When i point the TT at the audience, I do it for 1second before doing another action which naturally
hides the TT from view. (you can show it for 10seconds without being caught but why take the risk. 1 second is long enough for people to see that your hands are empty. "Don't challenge people" - Gary Darwin
Rule #2: Draw attention away from your "dirty" hand
. Use your eyes...look at your other hand. Draw attention there (or another place or whatsoever). Use your own creativity and imagination. There are lots of misdirections.
Rule #3: Remember! People are not looking out for a fake th***
, unless you're doing the vanishing s**k effect.
Pretty long post but I hope this helps you. PM me if you need more help.
