Double knit cast on

I am afraid that my head feels like it is in a vice. So if I don't make sense you'll understand why. Please email leanne@oknitting.com for explanations.
This technique works best working with bulky weight yarn.

Begin by casting on the desired number of stitches.
Begin to divide the stitches between two needles.
Knit the stitches onto the first needle.
Slip the stitches onto the second needle.

Or you may use two needles and a stitch holder.

Now, one side at a time, knit the stitches. Here are some quotes from some emails I have received on this topic:

'when [would] a knitter...use the Double Cast on Method.' -Jean

This method would be used when you wish to knit a project that has two sides: pockets or shoulders. I used this method when I designed the top down version of "When the Meadowlark sings". I am in the process of developing other patterns that utilize this technique. Looking for a kit in the fall.

This is "When the Meadowlark sings"

'Thank you for the email. ...The answer is yes and no.

No: If you slip the slipped stitches onto a stitch holder you need only to use one ball of yarn. Following this procedure will allow you to work one end at a time.

Yes: If, instead, you slip the slipped stitches onto a knitting needle then you will be able to use two balls of yarn. Following this procedure will allow you to work two ends alternatively.'
