A pleated window shade is disclosed having pleats that are uniform in appearance, that maintains its pleated shape over time in either a vertical or horizontal orientation, and is easy and inexpensive to manufacture. The shade is produced by running a flat segment of material over a serrated cutting wheel, which cuts a predetermined number of yarn segments at regular intervals. The cuts cause the material to fold or pleat along the axis of the cuts, resulting in a uniform, neat pleated appearance. The pleats may be made along the length of a roll of fabric to easily manufacture shades to cover large vertical spaces.
