Short sleeved top with open front. Garter stitch throughout. Body is knitted in one piece. Body and sleeves stitches are joined so that the yoke is knitted in one piece.
Underarm sleeves seamed by whip stitching. Grafting needed to join close lower arm hole.
Instructions given for 6 sizes, from XS (28” bust) up to 2X (57” bust)
Instructions including placing markers when the sleeves and body begin - looks fine on paper but they interfere with K3 together. Instead markers should be placed in the last row of body and sleeves - just before stitches are joined to knit the yoke.
Errata is listed in a thread in Group for Shetland Guild of Spinners, Knitters, Weavers and Dyers
