Knitting is a process by which a continuous length of yarn may be used to create fabric. This process can be accomplished by hand using knitting needles and yarn. Alternately it can be done by machine.

When knitting by hand, there are two methods that can be used which will give you different results. Flat knitting consists of working the stitches back and forth using two straight needles Circular knitting (known also as "knitting in the round") uses one needle with a point on both ends, joined in the middle by a long flexible cable. Knitting with the circular method gives you a seamless knitted tube. Alternately, you can knit in the round by using a set of four or five Double Pointed Needles (DPNs) which are then joined into a circle and knit around.

Essentially, when knitting you're pulling loops through other loops. This is done in two ways: knit, and purl. With those two stitches you can any stitch pattern. The most common stitch pattern is called stockinette stitch, this is created by knitting the stitches on one side of the fabric, and purling the stitches on the other side of the fabric. While this is the most popular stitch pattern it has its disadvantages. Any knitter can tell you that stockinette stitch curls both at the sides and the bottom so it can be hard to work with. If you tried to knit a scarf out of stockinette stitch, you would quickly find yourself with more of a tube than a scarf.

The earliest examples of knitting can be traced back to ancient Egyptian times and continued strong from there until the invention of machine knitting. This rendered hand knitting obsolete. Since then, knitting has gone in and out of popularity as a craft more than a life skill. Currently knitting is on the rise again among young people. With the popularity of the internet, many young knitters have taken to creating blogs about their projects and yarn.
