You are knitting a scarf using knit one row purl a row it keeps rolling up at the ends is there a way you can fix it without changing the pattern?

When you alternate between knit and purl rows (knit one row, purl one row, knit one row, purl one row, etc.) it is called the Stockinette stitch.

Unfortunately, the stockinette stitch always curls at the edges, and worse, there is no easy or perfect way to fix this problem. If you have a knowledge of crochet stitches, you could crochet an edging around the scarf, but this would change the whole look of the scarf, and there is no guarantee that it would work.

The best way to avoid this problem with future scarves is to knit it in garter stitch (knit every row), or another stitch that will not curl. Also, if you like the look of the stockinette stitch and would still like to use it, then work in stockinette, but at the beginning of each purl row, knit the first three stitches and the last three stitches. If you do this, remember to change the yarn to the back or front of the work depending on whether you are changing to the knit or purl stitch.
