Although the stitches in this jumper are fairly basic the jumper is constructed in a slightly unusual way using short rows, bias knitting and patchwork joining techniques. A fine mohair yarn is used double throughout.
Middle Back Section and Left Sleeve.
end of Row 1 should read ....p2, k3, **p2**, k2tog (last st with 1st from Lower Back stitches).
After the 4 rows of pattern the next line should read -
Rep Rows 1 - 4 twice more
Left Sleeve Edging, Top Back and Right Sleeve
I didn't include instructions on when to stop joining the top back to the top front for the neck opening.
When knitting the Top Front I suggest using a stitch marker to mark the start of the Front Neck shaping; this is the point where you want to stop joining the Top Back section to the Top Front section and then start joining again at the end of the Front Neck Shaping.
