Some machine manuals will give instruction for this type of cast on

Here are some variations:

• Open Cast on with a cast on Comb (shown in the video)
• Open Cast on with a wire
• Open Cast on with Ravel cord (shown in the video)

Most knitters graduate beyond these methods pretty quickly.

The following cast on methods leave open stitches to be worked later. For example, leave open stitches, then pick them up and hand knit some ribbing. Or turn the knitting, pick up open stitches and knit reverse stockinette.

• Scrap and Ravel Cast On
• Using a Cast on Rag

You will use these again and again
