Since it is January, many people have taken on the challenging January Aran Sweater from Elizabeth Zimmerman’s Knitter’s Almanac. The biggest hurdle for me (so far – we haven’t gotten to steeking yet, but I’m in extreme denial about that) has been mastering the traveling stitches, of which there are hundreds in the fishtrap pattern alone. Once you get used to the technique, it is pretty speedy. In the January Aran Sweater, you twist a regular knit stitch over a purl stitch in different directions, getting the effect of the knit stitch traveling either left or right and the purl sort of hiding behind. The knit stitch is always in the front, and it’s not unlike a one stitch cable. As many things in knitting, there are lots of ways to do things, but this is my favorite twisted stitch method. I learned it from Meg Swanson, in the Knitting Glossary DVD. Please excuse my lame picture edits, as I’m just using an old version of Microsoft Paint to add text and pointers.
Left Twist:

So, as you can see, you have the knit stitch, and the purl stitch, and the knit stitch needs to hop over the purl stitch to the left.

Piece of cake, right? Now comes the maneuver.

So, now that your stitches are on your right needle, you want to insert the left needle into the knit stitch which is the second stitch on your right needle.

So this is the tricky part – You have put the knit stitch on the left needle, and now you pull it to the left enough so the purl stitch pops off the right needle. You catch it again with the right needle, and now it is behind the knit stitch but still on the same needle. Place the purl stitch on the left needle, and then you can purl the first stitch, and knit the second. Make sure your stitches aren’t twisted, and you are good to go!

I hope that was clear enough! I do teach knitting classes, but it’s so different with stills on the internet. I feel like I should be standing with my back to you, size 15 needles up in the air giving you a visual.
Good luck traveling. I’m putting up the right twist up soon!
