I found these adorable videos on Laura's blog, It's Sew Chic. They were produced by Simplicity in 1948! They actually have excellent sewing information, and they're so fun to watch! You'll laugh at the intro to the first one where Betty waxes philosophical about her Home Ec. class... The first video talks about laying out patterns and how they are produced. The second shows basic dress construction, including stay stitching, constructing a dart and setting a sleeve, then ends with a drool worthy fashion show.
