Singer Featherweight

The Singer Featherweight is a model series of lockstitch domestic sewing machines produced by the Singer Manufacturing Company from 1933 to 1968. They are significant among vintage sewing machines for their continuing popularity, active use by quilters, and high collector's value.

Introduced as the model 221 during the 1933 World's Fair, the model boasted aluminum construction, small size, and a weight of only 11 pounds (5 kg). A free arm version, model 222k, was produced in Scotland from c.1954 to c.1964. It is estimated that Singer produced and sold some 3.0–3.5 million Featherweight machines during the model's lifetime.

Despite being out of production for many decades, Featherweights are sought after and used by quilters.
