How do you do knotted openwork pattern in knitting?

To create a knotted openwork pattern in knitting, you'll typically use a combination of yarn overs and knit two together (K2tog) stitches to form the open spaces. Start by knitting a base row, then on the next row, yarn over to create an open stitch, followed by K2tog to close the knot. Repeat this pattern across the row and continue for subsequent rows, maintaining the established pattern. Adjust the number of yarn overs and K2tog as desired for the size of the knots and the openness of the fabric.
