Definition of "godet"

A pie-shaped godet (the most common one), is usually cut with straight grain down the center of the piece of fabric, leaving bias edges on the sides.

Designs with godets, gussets, square or pointed yokes and shawl collars have seams with reverse corners, that is, an inward corner on one edge and an outward corner on the adjoining edge (as shown in the drawing on p. 52).

You can sew a godet into a slit cut perpendicular to a hem edge, but it's more common—and much easier—to insert it into a vertical panel seam, as shown here. Because godets are shaped pieces, often with a pronounced curve at the hem edge, they can be tricky to hem.

In contrast to conventional spinning, wind-up in high speed spinning is often carried out without godets, as shown earlier in Fig. 4.2(a). The absence of godets reduces capital costs and makes thread string-up simpler.

Drawing is accomplished between godets 3 and 4 by the different speeds of the two godet groups.
