BATH — Whitefield resident Sheila Knowles, a collector of antique dolls and sewing equipment, will give a demonstration of antique sewing machines at the Bath Antique Show and Sale on Sunday, Jan. 11.

Knowles has many machines in her collection and she will have several on hand at the show, including a selection of machines from the late 19th century to the 1960s, such a treadle and featherweight machines. Also on hand will be a hand-cranked machine once used to make socks for soldiers.

Knowles will explain how to care for old sewing machines and will have a inventory of replacement belts on hand. She will do binding and hemming and invites patrons to ask questions or even bring in their own machines for advice.

Now in its 26th year, the antique show takes place every four weeks during the winter and features dealers from the midcoast and beyond. An on-site café with food and beverages and dedicated seating is available.

The show will be open from 10 a.m. to 2 p.m. at the Bath Middle School, 6 Old Brunswick Road. Admission is $4. For more information, visit www.BathAntiquesShows.com.
