My friends have seen all of my best tricks (and all of the rubbish ones

So I thought, why don't I just improvise? Now, i would have thought that these tricks would have been absolutely rubbish, but some of them get amazing reactions!
What I basicallly do is think of one sleight (eg. a top palm) and use it. My little brother is usually very sharp, but I just did about 5 improvised tricks to him using the palm and he never spotted it once. I made a card appear under my leg, in a wallet thingy etc.
Now, I thought that this was pretty cool, as I was inventing patter and the effect on the spot, and to tell you the truth it is very easy.
The whole reason in this post is to show how simple sleights and methods can be used to create real 'off the cuff' tricks to great effect, and it greatly boosts your confidence (and also gets the creative juices flowing for when one wants to create an effect).
This principal of using a main sleight could also be applied to all kinds of magic to make real impromtu magic.
I would recommened anybody to try this, as you will then realise how easy it is to make up your own effects!
