The i-cord alone is used to make a cord. Use it for a purse, or for any time a long rope is needed. Do it this way: using double-pointed knitting needles in a size that works for your yarn weight, cast on 4.
See my page if you need help casting on.
Slip those 4 stitches to the opposite end of the needle and knit them. The yarn will be coming from the opposite end of the stitches which wraps around to make the cord. Do this over and over for as long as you need the cord to be, then bind off. (Watch the video.)
Knitter Elizabeth Zimmerman gets the credit for this simple idea.
Below is a video (not mine) showing how to begin, knit and bind-off the i-cord. It’s a bit slow and tedious, but that could be good for beginners.
How to Create An I-cord Edging
The i-cord edging neatens up the edge of a project. Like in my photos above of something I began knitting a long time ago. This would work on a scarf, blanket, dishcloth (good practice piece) or any place you want a nice edge.
But I couldn’t remember how I made that edge. And I can’t find info for edging like this anywhere. I think I’ve figured it out, as I knit a few more rows using this yarn. It’s the same basic idea as the i-cord – the yarn has to come from behind.
At the end of the row (whatever your pattern is) slip the last three stitches with the yarn in front.
This means you should include 3 extra stitches at both edges which will be knit at the beginning of the row and slipped at the end of each row.
Slip each of the last 3 stitches purl-wise and the yarn will end up in the back for the next row, where they will then be knit (all three stitches, one at a time) before carrying on the main part of the project.
How To Make a Simple Neat Edge
Scarves, blankets or other items knit back and forth may look best if the edge is done as follows:
At the end of each row purl the last stitch. When beginning the next row slip the first stitch then do the pattern. Either incorporate that stitch to replace one in the pattern or add an additional stitch to the pattern.
