Snip a wire clothes hanger into two 8-inch pieces using the blades on a pair of heavy pliers.
Bend each wire 90 degrees about 1 inch from its end.
Put another 90-degree bend in each wire about 3 inches from each untouched end. This creates a 3-inch-long handle for each wire. This bend should be in the opposite direction to the first 90-degree bend; when you look at the finished wire it should make a "Z" shape.
Hold one wire in each hand, grabbing each by its 3-inch handle.
Orient the wires so that the 1-inch sections past the bend at the other end of the wire are sitting parallel to the sides of the paver you wish to remove.
Wiggle the wires back and forth to work the short piece of wire down into the sand or stone dust between the pavers. Once they reach a depth just below the bottom of the paving stone, twist them inwards 90 degrees so that the short ends are caught underneath the paver.
Pull up on the wires to lift the paver up and out without disturbing the rest of the pattern.
