I tried different needles and yarns. I am now using a size 17 needle with 2 strands of Bernet felting natural wool.
set up 2 rows: k4, p1, k2, p1, k18, p1, k2,p1, k4
knit the knits, purl the purls
Row 1: K4,P1, Slip next stitch on cable needle and hold in back, K1, knit the stitch on the cable needle, p1,knit 3 sts; slip 3 stitches to a cable needle and hold them to the back of the work, knit 3 stitches, return the slipped stitches to the left needle and knit them; slip 3 stitches to a cable needle and hold them to the front of the work, knit 3 stitches, return the slipped stitches to the left needle and knit them; knit 3 sts
Row 2,4,6,8,10,12: Knit the knits and purl the purls
Row 7: K4,P1, slip 3 stitches to a cable needle and hold them to the front of the work, knit 3 stitches, return the slipped stitches to the left needle and knit them; knit 6 sts; slip 3 stitches to a cable needle and hold them to the back of the work, knit 3 stitches, return the slipped stitches to the left needle and knit them
Complete these 12 rows until desired length. Remove provisional cast on and do a 3 needle bind off to connect.
