The performer displays a simple "wallet" or 2 panel folder made of board. He shows the wallet empty, closes it, then opens it again, and two large (spring) flowers appear when the wallet is opened again. The flowers are removed, the wallet closed, and when opened again another two flowers of a different color appear. These are removed, wallet closed, and opened to produce another two flowers.  The effect is repeated over and over again, till you have produced five pairs of flowers from the empty wallet.

The flower wallet works on a most ingenious topological principal, so that even when you perform this effect you will be baffled at how it works.
