Hi,
The routine in Mark Wilson is a great place to start, it gives you an overview of a few good, basic techniques.
Failing that, many people recommend Steve Dacri's Spongeball Toolbox.
I am lucky enough to own a copy of Garcia's Encyclopaedia of Spongeball Magic, and whilst it is a fabulous read, and has some great routines, 90% you would never use.
The Purse Frame is a nice prop to learn, and offers some nice options, depending on your availability of pocket space.
Personally, because of the audience reactions, I now only ever use 3D sponge bunnies, but the balls are great to learn.
Be creative with your routines....
The yellow ones can be pollen, the black ones (hacked around with scissors) can be cigarette smoke/tar particles.
There's also an L&L "World's Greatest" DVD.
I also have the 2 x "Jon Jensen" pamphlets, which are quite good if you can find them./jensenjonprospongeball1.htm[/url]
Otherwise - I am sure you will find something
here...
Have fun
Bruce
