Quick Knitting Yarns- A thick yarn.... The advantage of these yarns is that they knit up quickly, but the result is clumsy and not altogether satisfactory. For children's dressing-gowns and very heavy sports wear they are sometimes useful.
Margaret Murray and Jane Koster, Practical Knitting Illustrated: the key to hundreds of garments you can make yourself, 1947. This is considered one of the classics on English knitting. If you look at knitting patterns before the 1950s, you are hard pressed to find bulky weight yarns being used, or even worsted weight yarns. In fact, most of the vintage patterns I find seem to be using sock yarn or smaller. I don’t know if it was the new leisure American had after World War II, and thus heavier sweaters were more needed for sports, or if women were coping with their Baby Boom offspring and felt they had less time for knitting, but it’s clear that you start to see “bulky” yarn patterns in the 1950s. While some were today’s bulky weight, others seem more like aran, or even worsted weight. They were clearly used to finer yarns and the more sophisticated patterns that resulted.
