One of the things I keep a constant eye open (typically Ebay) are lots of loose pattern leaflets. As they are typically just stacks of paper, I never know what I'm actually going to get. It's kind of like buying a mystery box. It's also a gamble, the leaflets may, or may not, be public domain documents that I can use. But, there are almost always grand surprises. Like this one .....
Apparently, Spool Cotton Company hosted contests for teen girls in Home Ec classes. The teacher would send for the packets and incorporate into their class instruction.
The packet would include directions for a number of easy crochet items from which the students could choose.
This particular leaflet is titled Stitch in Time, Monthly News Bulletin, March 1940, It is Volume 10, No. 6. I have more of these Stitch in Time Newsletters in my 'pending' stack. They cover a wide variety of topics, however, and are not just contests.
You'll find these patterns in the Crochet Collars or Crochet Hats Section of the shop.
Thanks for dropping by,
