This cast-on is stretchy and nearly invisible, and a good choice for things like cuff-down socks and hat brims – items that have ribbing and require some extra stretch.
A question came up when I was working this cast-on – can any rib combination work? I’ve tested it out, and the answer is yes. Just watch how the stitches are forming on the needle as you work them. Working multiple K or P stitches together can make a funny twist on the stitches, but they can be straightened out.
