In the Datafile #29 SSW D.III~D.IV on page 12 top photo clearly shows the
fabric applied spanwise.m As I remember reading it, the times one would not
want to apply the fabric spanwise is only in the case where the width of the
fabric is not wide enough to cover the wing in one pass. I don't think it
would be a good thing to have a seam in the fabric right under the low
pressure zone on an airfoil.
