The number of pins depends upon the complexity and size of the component and
the complexity of the pattern and the slipperiness of the fabric surface. The pins should
not be placed too close to the sides of the pattern pieces, or they will impede the sub-
sequent cutting process. The use of pins significantly decreases the displacement of
material plies and increases the quality and coordination of the patterning.
After respreading, the components are cut for the second time, and the fabric allow-
ance is removed, using a band-knife machine.
