Video: Provisional Cast-On
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.
1. To cast on an even number of stitches, start with a yarnover.
2. To cast on an odd number of stitches, start by bringing your needle under the waste yarn or circular needle.
3. Make sure that your last stitch is not a yarnover - if it is, it will fall off the needle.
4. When you remove the waste yarn and put the stitches on your left-hand needle, insert the needle from front to back to make sure the stitches are facing the right way. If you have used a circular needle, this won't be an issue.
