NeedlesNeedles comes in a variety of shapes and sizes. There are three types of knitting needles:
Straight Needles - They have a point on one end and a flat or rounded head on the other. straight needles are available in either 10" or 14" lengths and in a variety of widths.
Double Pointed Needles - As the name implies, these have points at both ends. They are used for tubular projects such as socks. Most people recommend double pointed needles until you've mastered using the straight needles.
Circular Needles - These are two needles joined by a cord. They are often used for circular projects (such as hats) and are especially useful for projects with a large number of stitches. Needles also come in a variety of sizes - all in an effort to help achieve the desired width and of your stitch. Each needle has a millimeter range that corresponds to a U.S. size range so be careful to choose the right size designation for your project.
