Nålebinding is a fabric creation technique pre-dating both knitting and crochet. The technique is distinct from crochet in that it involves passing the full length of the working thread through each loop, unlike crochet where the work is formed only of loops, never involving the free end. It also differs from knitting in that lengths must be pieced together during the process of nålebinding, rather than a continuous strand of yarn that can easily be pulled out.
