Double FLOW is Vivek Singhi's take on blending cardistry and magic with a sandwich effect in a smooth F.L.O.W. A combination of a smooth flourish and control, the cards literally flow like water crawling around each other. End with the spectators selected card sandwiched between the 2 jokers. Use it as a flourish, a control, a sandwich effect or all three. Double FLOW is super fun, and very versatile. As a bonus, the download includes explanations for both variations from the F.L.O.W releases.
