ABOUT THE PATTERN
One evening I was swatching some slip-stitch textured patterns in plushy emerald-green yarn, while in the background my teenage daughters were re-watching the first Twilight movie. Next morning I looked at my swatches and realized I was unconsciously trying to replicate the gorgeous rolling hills covered with pine forests and swirls of mist that I saw in the movie (filmed in Oregon, hence the pattern name).
This thin but warm pullover is exactly what you need for a walk in the fall in a forest or urban jungle.

CONSTRUCTION
The yoke is knit flat sideways in garter stitch with short rows for shaping and slip-stitch print (can also be done in a contrast color). It is then seamed at the back and trimmed with I-cord along the neck opening. Smallest children sizes have a button closure at the back to make putting it on easier.
After that, selvedge edge stitches are picked up and back is raised for a better fit (using more short rows). Sleeves are separated from the body, casting on extra stitches in the underarms.
Body is worked straight (A-line & fitted mods possible – see Appendix) top-down in the round with optional horizontal bust darts. The hem is finished with I-cord bind-off to mimic the yoke.
Sleeves are also knit top-down in the round with two shaping options: slightly tapered, or bishop-style, both options finished with a garter cuff and I-cord bind-off.

MATERIALS AND TOOLS

Yarn: sport-weight to DK wool (can be 200-350m/220-380yds per 100g/3.5oz, as long as it gives gauge).
There is a pattern modification for print in one or multiple contrast colors (see sample photo below).
I do NOT recommend using 100% superwash merino or >50% alpaca as those might sag considerably in wear.
Choose yarns with little to no halo to best show off the print. You can use a solid / tonal, but I would avoid highly variegated as it will “muddy” the print.

The sample was knit out of ‘Yak Mel’ by Pecci Filaty (70% merino, 30% yak; 650m/700yds per 100g/3.5oz – held double); colorway ‘Malachite’.

Needles:
• Main: 3.5mm/US4 (or size to get stockinette gauge) circulars on a 40-100cm/16-40” cable, depending on the size worked + DPNs for the sleeves, if you prefer them to magic loop (for magic loop you may need 0.25mm / 1 US size larger needles);
• Smaller: 3mm/US2.5 (or ~0.5mm/ 2 US sizes smaller than main) same cable length as the main ones + DPN’s for the I-cords on the neckband, hem and cuffs.
I-cords: most knitters use a smaller needle, but if you are a very tight knitter, you might even have to go up a needle size for I-cord – make sure to check that it lays flat and goes over the head easily.
Notions: waste yarn, crochet hook, cable needle (optional), stitch markers, row counter, tape measure, tapestry needle, scissors; for children sizes up to and including 6-7 y.o. – 1 button (~8-12mm/ ¼-½” in diameter)

GAUGE (PER 1010CM/ 44” AFTER WET-BLOCKING)
• Stockinette: 20 stitches by 32-34 rows (depends on your yarn qualities) – on main needles;
• Garter stitch: 20 stitches by 40 rows (20 garter ridges) – on smaller needles
