This method of casting on is also known as the “magic toe-up cast-on,” due to its popular use in beginning toe-up sock construction. Instructions were first published in an issue of the on-line knitting magazine Knitty.com.
Benefits and Drawbacks
This cast-on creates a continuously knitted piece with no discernible beginning, much like provisional cast-ons. However, unlike provisional cast-ons, there are no further steps to take (such as taking the cast-on out and picking up loose stitches). Once this cast-on is finished, the piece is ready to be knit from both directions.
