Ad for Reynolds Yarns from McCall's Needlework & Crafts, Spring-Summer 1968.
Back then you could purchase the instructions for all three ensembles for a mere 25 cents. Clearly during the Sixties knitting was far more than a hobby. It was a lifestyle! A depraved lifestyle, involving avian cosplay and disturbingly sharp - and phallic - needles.
Reynolds has since disavowed their wild jet setting ways, and the patterns for these alternative flight suits are sadly no longer available. Instead, you can find pastel sweater patterns in an assortment of inoffensive designs here: http://www.calyarn.com/patternindex3.htm
However, as they currently have yarns named "Frisky", "Saucy", and "Olé Olé", there may still be life in the old girl yet.
For even more snark:
Baby, baby, make it hurt so good!
