STEP-BY-STEP

SL1, K1, PSSO

Insert the point of the right-hand needle into the next stitch as if you were to knit, but slip the stitch off and on to the right-hand needle.

Knit the next stitch as normal.

Now insert the left-hand needle into the slipped stitch on the right-hand needle and lift it over the knitted stitch.

Continue knitting until the end of the row. This decrease forms a slant which lies to the left.
