How to Knit - Casting On

CO = cast on

Casting On is the term for making the foundation row of stitches on your needle.

To begin, you will need a pair of knitting needles and a skein (also called a 'ball' or a 'hank') of yarn. The terms 'skein' , 'ball' and 'hank' refers to the form factor for the bulk yarn.

  1. A 'skein' is the form that the yarn is in when it wound by the manufacturing equipment. Some skeins are designed so that you can pull the yarn from the inside as well as the outside. These are called 'pull skeins.'
  2. A 'ball' is yarn that has been rolled into a ball (sometimes done by knitters for convenience or to divide a skein into multiple quantities for use)
  3. A 'hank' is the yarn wound loosely in a circle. Hanks are common in hand-spun or hand-dyed yarn, but are not common in commercially-prepared product. If your yarn is in a hank, it will tangle easily and it is advisable to roll it into a ball before beginning work.

In these instructions, we use the term 'ball' to describe the yarn in bulk, but the term 'skein' would be equally accurate -- we do not mean that you have to wind your skein into a ball!

Are you left handed?This tutorial teaches 'English-style' in which the yarn is held in and manipulated by the right hand. If you are left-handed and you find the method explained in this tutorial uncomfortable, you may want to look for a source where you can learn Continental-style knitting (in which the yarn is manipulated by the left hand rather than the right one) or look for a source where you can learn mirror knitting (a process where the knitter executes a true inverse of the method explained in this tutorial and which does not require that the knitter reverse the pattern.)

Whatever you do, we advise against starting out with a method where you routinely have to rewrite the pattern instructions because this is a technique that beginners often find difficult.

There are many different methods of casting on. The method described in this tutorial is called the 'knitting cast-on. Other popular methods include

  1. the single-stitch cast-on,
  2. the long-tail cast-on,
  3. the cable cast-on,
  4. the double-knitted cast-on and
  5. the crochet edge cast-on.

We recommend learning the knitting cast-on as your first method because it is simple and leaves an edge that stretches well. After you become more expert, you may wish to find out more about the other methods.

We offer this tutorial in both written and video format.

Illustrated Instructions

Working on a flat surface, begin by placing the ball of yarn to your left and holding the free end ('tail') of the yarn in your right hand. Make a very loose loop in the yarn about 5 or 6 inches (12 or 15 cm) from the free end of the yarn (the tail) by looping the yarn from the right to the left. The tail will be front and on top of the strand that comes from the ball of yarn. Then, pass the tail behind the strand, pulling the tail very gently to the right so that it passes behind the loop and the end of the yarn lies to the right of the loop and the ball of yarn.

Holding one needle in your right hand and moving your needle upwards over the bottom strand, slide the tip of the needle under the strand of yarn that comes from the tail, pick it up and pull it upwards through the loop. Gently pull the tail of the yarn with your right hand so that you tighten the yarn around the needle. This is your first stitch.

Put the needle with the loop on it in your left hand, grasping it between the thumb and forefinger of your left hand as you might hold a pencil for writing, but with the tip up. The yarn from your ball will be IN BACK and on the bottom of the left needle; the tail will be coming off the front on the bottom. Pick up and hold other needle in your right hand, as you would hold a pencil, but with the tip pointed up. Note: Knitting needles are deliberately slippery so that the yarn can slide easily on them while knitting; keeping the tips up keeps the yarn from sliding off when you don't want it to!

With a motion from front to back, insert the tip of your empty right needle into the loop on the left needle, underneath the left needle . The needles will cross inside the loop with the right needle under the left one.

Adjust your thumb so that you are gently gripping both needles between the thumb and forefinger of your left hand. The right needle is still on the bottom.

There are two strands of yarn hanging down from the stitch. One is the tail of the yarn and the other strand goes to the ball of yarn. You will be working with the strand that goes to the ball of yarn. Holding the yarn with your right hand and keeping the needles in your left, bring the strand of yarn underneath the right needle. Wrap the strand around the tip of the right needle, starting underneath from the right, going around the back to the left and bringing the yarn up over the needle to the right so that the yarn is wrapped in a clockwise motion (the direction that the hands on the clock move). The strand of yarn will be on your right when you have finished.

Pull the yarn with your right pointer finger to tighten it so that it is not loose on the needle. Keeping the yarn wrapped on the right needle, pull the tip of the right needle towards you, out from below the left needle and up through the center of the stitch on the left needle. Then slide the tip of the right needle so that it is now on top of the left needle and the yarn that is wrapped around it has been pulled through the stitch that is on the left needle. When you are finished, the tips of your needles will be crossed with the tip of the right needle on top and the left one below. There is a loop on the right needle that has been pulled up through the stitch. Don't get discouraged if you don't get this on the first try! There is a 'knack' to moving the right needle and the loop on it so that the loop does not slide off when making this motion. This can take several tries before it becomes natural.

Now you have one loop on each needle with the right needle resting on top of the left needle. Elongate the pulled-through loop on the right needle by pulling it gently. This will soon be your second cast-on stitch!

Transfer the new cast-on stitch from the right needle to the left needle by inserting the tip of the left needle into the loop of the stitch that you have just created on the right needle and slipping the stitch from the right needle to the left needle.

You now have 2 loops ('cast-on stitches') on your left needle!

Repeat steps 4 through 9 until you have the desired number of stitches on the left needle. When you have as many stitches on the needle as are required by your pattern, your cast-on is complete!
