Why this method?
I show you a more suitable method for cast on 1/1 ribbing. This method is extensible and gives a nice finish compared to the classical technique.
It’s especially easy if you already know the cable cast on.
1. Make 1 loop on your left needle.
2. Insert the right needle in front of the loop and knit, place this formed stitch on the left needle. You get 2 stitches.
3. With yarn in front, insert your right needle from back to front between the last two stitches and purl, place this formed stitch on the left needle. You get 3 stitches.
4. With yarn in back, insert the right needle from front to back between the last two stitches and knit, place this formed stitch on the left needle. You get 4 stitches.
5. Repeat steps 3 and 4 to the desired number of stitches.
On the next row, knit stitches as in picture above. Normally, the first stitch is a knit stitch and then purl stitch if you have a even number of stitches.
You may already know the cable cast-on method. It is a method that I use all the time, which consists of knitting the stitches. I do not like to cast on the stitches with my fingers as long-tail cast on because you always have to plan some lengths, it’s difficult to give a precise measure especially when you have a lot of stitches to cast on.
Like you, I often finish my sweaters with ribs for the sleeves or the buttonhole band or something else. You can see that it’s always a bit of a challenge to bind off the ribs, because when you bind off with the classic technique, that is to say bind off stitches one by one as it is, it’s simple but the rendering is not pretty and lacks flexibility.
