This is for right handed cast on I will put this and a left handed example on NezumiWorld which is in the process of been updated very soon.

1. For the bobble yarn I used a knit cast on, normally to begin I use a slip knot but with the bobble yarn this looked untidy (and was a bit fiddly) so I made a simple knot.
Insert the right hand needle through the stitch (knot) on the left hand needle as you would to make a normal knit stitch.

2.Yarn over the right hand needle making sure you use the yarn between the bobbles.

3. Pull loop through the stitch, the bobble should not be pull through the stitch.

4. The stitch (knit stitch) you just made on the right hand needle is now transferred back onto the left hand needle.

5. Repeat making a knit stitch than transferring them back to the left hand needle until the required number of stitches are achieved
