This is a great idea...the gradually dawning reveal at the end of most routines is an amazing thing
to watch as your audience "gets it"
Some of the routines described seem a bit torturous and
a bit similar to "counting card tricks". One gets the idea that some of them were included to pad
out the instructions.
But the majority of routines that aren't like that, are killers.
The card markings are a little too subtle for my nearly-60-year-old eyes and the low light
situations I usually work in, but they are very clever an extend the uses of these cards a long way.
You can also come up with your own routines as these sets of cards are a true utility item
that really do facilitate your imagination to take off.
Highly recommended and a great
price!
