The cast-on stitch is an embroidery stitch that can be used for embroidering flowers or any other pattern to which it is desired to give relief without using the “stumpwork” technique.

Unfortunately, I know that the picture is not very explicit than for those who do not know this stitch this is what you need to know.

The stitch is worked like a simple bullion stitch but instead of winding the thread around the needle it is necessary to “cast on” stitches like to begin a knitting and then pass the needle through.

You will find HERE a very well done tutorial that will show you how well to succeed with this stitch.
