Up until the end of the 1970s, there were several companies producing or distributing rug yarn under their own names. There have been buy-outs, takeovers and dissolutions, but their yarns are often found on online auctions. This illustrated guide is by no means comprehensive! I’ve tried to group brands under their current or last parent companies, giving the type of fibre where possible.
