As written, this cute and simple little pullover sweater is knit in stockinette stitch, with garter stitch edges in a contrast color. You could, of course, knit the entire sweater in just one color.
Pattern provides clear instructions for 2 sizes (small - 22” chest and large - 24” chest), with detailed instructions for all shaping.
Sweater front and back are knit separately, and joined at the shoulders. Sleeve stitches are picked up at the armhole edge and knit down to the cuff.

Recommended yarn is Luisa Harding Cassia, 2-3 skeins in Main Color and 1 skein in Contrast Color.
Sample sweater used Lime (color 108) as the Main Color, and Earth (color 111) as the Contrast Color.
Recommended gauge is 5.5 stitches and 7.5 rows per inch in stockinette stitch, using larger needles.
Recommended needles are size 6 (for body) and size 4 (for garter stitch edges). A 16” circular needle is required for the neckband, in the smaller size.
Change needle size as necessary, for correct gauge!
