Knitted cast-on
You will use this cast-on when you need to add five, ten or maybe twenty stitches to one side of your work. Pay close attention to your tension, because this cast-on has a tendonciy to be fairly tight.
Cable cast-on
This cast-on resembles the Knitted cast-on. I prefer using the cable cast-on over the Knitted cast-on because I think you achieve a stretchier edge. It should also be noted that if you use either of these cast-ons as the bottom edge of your garment, the front edge will be facing you so you can begin your knitting with a knit row.
(Chain stitch cast-on)
This cast-on is reversible, which means the edge looks the same on the knit side as it does on the purl side. The bottom edge creates a chain effect, hence the name chain stitch cast-on. But we create this cast-on with a crochet hook, hence the name crochet cast-on. So make sure you have a crochet hook around.
(Also known as an invisible cast-on)
This is a more advanced cast-on suitable for double knitting or ribs. The result of this cast-on is wonderful. The bottom edge of your ribbing is snug but very stretchy.
(Another way to create a Double Knit cast-on)
This is another way to achieve the same results as the double knit cast-on. Try both and see which way you prefer.
