Bobbins and the machinery they ran on were some of the greatest inventions of the Victorian Era. Originally created to manage the piles of thread and yarn that would be mechanically woven into cloth, bobbins helped to revolutionize textile manufacturing. The automated weaving machines would have hundreds of spindles operating simultaneously, with each spindle holding a bobbin that either released or collected the thread. Most mills had wooden bobbins made specifically for their machinery, which accounts for the many varied shapes and sizes of these spools. Traditional wooden bobbins have been retired from current manufacturing. Modern economics does not favor the use of wooden bobbins since a great deal of handwork is involved in making them. And wooden bobbins are not well suited for today’s synthetic fibers and high-speed machinery. Primarily made from ash, birch, and other hardwoods, bobbins have withstood the test of time. Each one has its own “battle scars” that give it unique character.
