The standard provisional cast-on uses a circular needle or a piece of waste yarn to hold the stitches until you are ready to work them.
I love the idea of using a circular needle to hold the stitches because when you are ready to knit them they are already on the needle and ready to go.
However, if you’re going to be turning your work a lot and don’t want a circular needle hanging down and banging around, you can use a piece of waste yarn.
This method works for Magic Loop as well as regular round knitting on circular needles.
