More and more Americans are moving towards US-made products to support domestic companies. In recent years, there’s been growing demand for wool yarn that's completely produced in the United States, from sheep to skin. One reason could be that consumers are turning back to wool because of the environmental risks of microplastics in garments made from synthetics such as acrylic, nylon and polyester. The microplastics are released into waterways when the synthetic garments are washed.

Locally sourced yarn helps not only the environment but local businesses too. Shopping local is allowing farmers to raise and keep their animals on the farm. The farm-to-table movement of eating local, shopping local -- basically the major slow food movement -- laid the ground work for the knitting industry. Business is growing for fiber artists and companies that focus on producing high-quality, ethically sourced yarn with attention to their environmental impact.

Yarn company Brooklyn Tweed was founded in 2010 to preserve, support and sustain American textile production by doing business with sheep farmers, fiber mills and dyers across the United States. Most garments worn in the United States in the first half of the 20th century were American-made, but the decline of the American textile industry began after World War II.
