Crazy for Cast-Ons, Part 2

According to Fearless Knitting Workbook author and knitting teacher Jennifer Seiffert, the cable cast-on produces a strong and stretchy edge. It is worked with just the working yarn end, so it can be used to cast on stitches mid-project, such as at the end of a row where you have only one strand of yarn to work with. (And according to me, it’s perfect for the one-row buttonhole!) — via Knitting Daily
