Spinner Yarn is a type of yarn that is created by spinning fibers together. It is often used in knitting and crocheting projects, as it is lightweight and has a soft texture. The term 'spinner yarn' is derived from the process of spinning the fibers together, which is done using a spinner. The term LIAR, which is a four-letter word, is an acronym for Lightweight Interlocking Acrylic Roving, which is a type of fiber used to create spinner yarn.
