A Cable Cast On is a good way to cast on stitches in the middle of your knitting. Often a pattern asks you to be knitting along and then says, cast on some number of stitches. I almost always use a Cable Cast On in that situation. This example comes from our Baby Bloomers Project Journal.
Free - his little project is a perfect gift and it knits up hella quick. If you haven’t tried to do any cabling yet, or if you want a reason to learn the provisional cast-on or kitchener stitch, this is a good reason to do so.
