French knitting tool. The technique is to wrap the yarn around the spool's pegs. The yarn is then lifted over, thereby creating stitches. This process is repeated continually until the project is complete.
Spool knitting is a traditional way to teach children the basic principles of knitting. Spool knitters typically have four or five pegs (or brass nails), although the number can range from sixteen to more than one hundred.
Many things can be made from the resulting tube. For example, it can be wound in a spiral to produce a mat or rug or, if a larger spool with more nails is used, a sock or a hat could be made.
