Decreasing at the beginning of a row

When forming an armhole or neckline shaping, binding/casting off is done at the beginning of the row.

Slip 1 stitch purlwise (as if to purl it) onto RH needle, knit the next stitch, with the tip of the LH needle pass the slipped stitch over the knitted stitch.

Knit 1 stitch, pass the second stitch on RH needle over the new stitch. Repeat for the required number of stitches to be bound/cast off, making sure that the tension is not too tight. Bind/cast off the stitches in the same manner at the beginning of the next row = wrong side, but working them in purl.

On the following row, continue the shap-ing as indicated in the instructions until the rounded form of the armhole or neckline has been completed.
