If you'd like to do this by hand, try y = (6.28 x cos(x/r)) / n, where y is the width of the wedge at x, r is the radius of the globe, and n is the number of wedges. Make sure cos calculates in radians. No wedge cut from flat paper will fit perfectly over a globe, but the fit gets better the more wedges you use. Wetting the paper will probably make it a little more stretchable, depending on the type of paper, and easier to fit. LEF
