How to knit marlisle colourwork in the round

My Oil Paint Cowl pattern features a type of colourwork called ‘marlisle’, where the foreground pattern is stranded in the usual way, but the background is marled, i.e. it’s worked with both colours of yarn held together. Odd-numbered rounds: - knit foreground stitches with CC (contrast colour) only, holding the MC (main colour) behind - to keep floats loose: stretch out the foreground stitches just worked - knit background stitches with both colours held together. Even-numbered rounds: - knit foreground stitches with CC only, holding the MC behind - to keep floats loose: stretch out the foreground stitches just worked - purl background stitches with both colours held together.
