Knitting mittens requires knitting needles, yarn, a yarn needle and a crochet hook. A notebook, pen and tape measure are useful, but are not necessary.
The size, weight and material of knitting needles vary. Many knitting needles are made of metal, plastic or wood. Types of yarn also vary, though a warm material such as wool is often recommended for knitting mittens. A yarn needle helps to connect different pieces of yarn or string, while a crochet hook helps save dropped stitches. A notebook, pen and tape measure may be useful for beginners who wish to record progress on a specific pattern.
