This pattern is for a 3 colour slip-stitch striped sweater with polo neck or crew neck, to fit Sasha or Gregor dolls.
The sweater is knit in the round from the neck down with raglan shaping until separating for the sleeves, then knit flat and finished by seaming sleeve and side seams.

A similar pattern knitted in 2 colours was used for the sweater that is shown in the pattern photograph of the Sasha Doll Hat and Mittens-Scarf on the Sasha Doll Style blog, see it here.

You will need 3 or 2 colours of Fingering yarn, a MC and two or one CC. MC is also used for ribbing.
A self-striping yarn can be used as the CC.

Gauge of 7 sts and 9 rows for 1” knit in stockinette using US 3 / 3.25 mm needles. You may need to use smaller or larger needles to achieve gauge.

Pattern is written for knitting with 5 DPNs but is easily adapted for use with circulars and stitch markers.

A larger needle may be used for casting on to make sure the sweater will fit over the doll’s head, which measures 10 1/2” or 26.7 cm around.
