It is a simple 1×1 rib-stitch scarf made with lace-weight cashmere yarn, though it also works well with other yarn weights.

It creates a neat edge by adding two selvedge stitches at the beginning and end of each row, along with two slip-stitch rib rows at the start and end of the scarf.

To prevent the ends from curling, you may knit a bit tighter or use a smaller needle size for the first and last two rows.
