These are fuzzy cuts from tube socks. Chain them together for a cushy, fuzzy rug. The second image shows part of a rug woven with chained loopers. The first image shows half a pound of loopers.
These loopers can be dyed with fiber reactive dyes. The result is a heathered look due to the elastic content. Washing is recommended prior to dyeing to remove any oils from the manufacturing process.
Sold by the pound.
