If a stitch isn't worked again on the same row, you slip it purlwise so when you come to it again on the next row it's not twisted. Juat insert the needle as if to purl it, but move it to the R needle. And you move the yarn front or back as directed in the pattern. The brick pattern will form as you work the sts, you'll be able to see it after a few rows.
