At no time does the weaving yarn actually knit a stitch (or enter the hooks of the needles). The weaving yarn is carried over or under each needle to create the design.

Because the weaving yarn is carried across the purl side of the knitting, the purl side us generally used as the right (or public) side. But certain yarn combinations and stitch patterns can create interesting fabrics with the knit side as the right side.

Try using ribbon or strips of fabric - the sky's the limit!
