Q&A for How to Knit an I Cord

Acrylic yarn is great because it's inexpensive, can last for a long time, and hold up to being in the washing machine.

You should block your project. Blocking involves soaking or steaming the knitting and drying it to get the fibers to even out. Besides this, do not sew the knitted pieces together too tight or too loose. The sewing should match the tension of the knitting.

You can cast on more stitches, but it might not work as well.

Yes, you can. It would make a thicker I cord. Different colors would make it colorful, too.

You can use any yarn weight to make an I cord. Of course, the thinner the yarn, the smaller the cord, as thicker yarn will yield a larger cord.

Follow the instructions in the article and pick up and knit 1 stitch off your square at the end of the row. You will be adding one extra stitch to the I-cord when you knit onto the square. Repeat each row in this way. To turn a corner, do not pick up a stitch for two rows. Go back to picking up and knitting a stitch on the next side of your square. Finish off by casting off and sewing the tail into the start of the I-cord.

The length of the cord depends on the needle size you use regardless of the yarn weight. The needle size gives the height of each stitch. When you multiply the number of rows by that height, you will get the length of your I-cord. The worsted weight gives thickness to your cord. The higher the number, the thicker the cord.
