Hold the needles as you would for making a knit stitch, but bring the yarn from the ball to the front of the work. If you hold the yarn in the left hand, make sure to take the yarn over the needle before pulling it through; wrapping under the needle may seem easier, but your stitches will face the wrong way. Work into each stitch on the left needle in turn to complete a purl row.
In and around
Taking the right needle behind and under the left needle, insert it from right to left (called “purlwise”) into the front of the first stitch; take yarn over and around the right needle.
Through
Dip the tip of the right needle, taking it away from you to draw a loop of yarn through the stitch on the left needle.
And off
Drop stitch off the left needle to make a new purl stitch on the right needle.
HELP
My knitting is uneven, what can I do?
If you have just the odd loose stitch, use the tip of a bluntpointed needle to ease the spare yarn along the row to the side edge, where it can be darned into the seam.
