Hello everyone! I am a new member and very excited about this website. I am looking for an old favorite of mine. I have had no luck in any searches and any help will of course be greatly appreciated. I describe the effect as follows; A volunteer chooses one of four different cards by sliding it forward from the rest. The cards all have a brilliantly colored star (red, blue, green, and yellow) to choose from on the face side. The finale is when his/her card is shown on the back side, it is not only a different color(blue or orange as I can best remember) from the rest, but contains either a different phrase such as "Your card" or "First Choice" while the phrases on the other three cards seem to be the same. Does this ring a bell with anyone and do you know where I can purchase?

Where can I buy blank packet size cards?

Blank both sides cards/Double blanks can be purchased from most large magic dealers by the deck. Try Card Collection in the UK for several choices or if in the USA try Royal Magic for a cheaper Bridge sized option.

Sounds like you are describing a variation on a very old, multiple o--- trick. Mine used just three cards and was called Mental Choice. Most magic dealers offer a version of this trick, usually with three choices.
