sewing patterns

Sewing patterns are templates—usually printed on tissue paper or cardboard—that guide cutting and assembling fabric into garments or other sewn items.

They include markings for seams, darts, and grain lines.

Commercial patterns from companies like McCall's or Butterick come in envelopes with instructions and multiple sizes.

Experienced sewists may draft their own patterns or modify existing ones: I found a vintage sewing pattern for a 1950s dress.
