That bag has long ago left this house, all that remains are small bobbins of Brown Sheep that remind me of my misplaced ambition.
I am not the most able Continental knitter, but once you learn the rhythm it becomes easier, and I know with practice I will get better.
The nice thing about knitting two color stranded in the round is you never ever have to purl back.
When you know you are creating a garment, and for this purpose we will use the example of the cowl, that has the need of an opening, but you want to knit it in the round so you can knit the entire garment, you must create a "steek", simply put extra stitches that you knit, creating extra fabric that you will then "capture" so you don't lose your live knitting.
Here you can see the "steek", we knit a border for 20 rows, then placed markers, cast on (in this case using the "e" loop method) an additional 5 stitches.
Long ago when I was an innocent and intrepid newbie I embarked on an intarsia carpet bag - it was featured in Interweave sometime in '03 or '04 (and if I was feeling charitable about intarsia I might have looked up the pattern).
Thankfully it was felted, otherwise I would have had a multi colored sieve.
You read that correctly, you CUT into your KNITTING.
Once you commit to "steeking" there is no turning back.
Where you need to take care in creating a "steek" is making sure that your seams are solid, if in doubt sew another seam.
Steeks to create a small ridge under your borders, and so are probably not for every project, but I am planning to knit a two stranded ski sweater, and I tell you being able to knit it all the way with small seam ridges in the armholes and the cowl neck are a very small price to pay. Lastly here is the practice cowl made out of rope, I mean acrylic.
And if we were all worms this would be perfect, we could knit tubes for days!
