With the Triyang collection, you have the option of using just one or two of the sections of this pattern, combined with one or two sections of the other patterns, and/or garter stitch or stockinette.

Same as the Triyang pattern, Twou is constructed modularly, with no picked up stitches, in 3 narrow triangles, joining to make a large, slightly asymmetrical triangle.

Twou is sized based on gauge - it is pictured in a larger size, which is the DK weight yarn held double stranded, making an aran weight (on size US 8 needles for a very dense gauge), and a smaller size, in the DK weight yarn on size US 4 needles, for a small shawlette. (Detailed sizing info is below.)

All stitch patterns are charted and written; the charts and written rows are on their own pages so that if you want to work from only the charts, you can skip printing 4 pages of written rows, and if you want to use only the written, you can skip printing 4 pages of charts.

The pattern also includes a schematic, construction/technique notes, close-up photos of the stitch patterns.

you need
‣ approx 250-500 yards / 230-460 meters DK-bulky weight yarn, in a solid or semi-solid colorway - yarn weight/gauge determines size
-- smaller sample is in Infinite Twist Helix DK weight (Spooky Purple), approx 285 yards / 260 meters used
-- larger sample is in Infinite Twist Helix DK weight (Spooky Purple) held double stranded, to make an aran weight, approx 460 yards / 420 meters used (of aran weight; approx 920 yards / 840 meters of the Helix)
‣ needles sized to match yarn - a circular needle 32”/80cm or longer for holding the stitches

Choose your yarn based on the kind of lace piece you want. Both samples were knit at a standard, not loose gauge, for relatively dense lace fabric (the larger is especially dense), in 100% wool, semi-solid plied yarn. You can get very different looks with a more drapey yarn, and/or a loosely worked gauge, for more open lace, or a true-solid colorway, etc.

sizing
Size will depend on your yarn weight/gauge. Using a gauge smaller than 6 stitches per inch will make a very small shawl, so only larger sizes are given (around DK and heavier).
‣ 6 sts/inch/2.5cm makes a length around 48 inches / 122 cm.
‣ 5.5 sts/inch/2.5cm makes a length around 51 inches / 130 cm.
‣ 5 sts/inch/2.5cm makes a length around 56 inches / 142 cm.
‣ 4.5 sts/inch/2.5cm makes a length around 62 inches / 157 cm.
‣ 4 sts/inch/2.5cm makes a length around 69 inches / 175 cm.
‣ 3.5 sts/inch/2.5cm makes a length around 78 inches / 198 cm.
These are just general guidelines; results will vary depending on yarn, exact gauge, how you block it, etc.

Smaller sample length: 50 inches / 127 cm; height: 15 inches / 38 cm (size US 4 (3.5mm) needles, for a blocked stockinette gauge of approx 23 sts per 4 inches / 10 cm).

Larger sample length: 68 inches / 173 cm; height: 22 inches / 56 cm (size US 8 (5mm) needles, for a blocked stockinette gauge of approx 15 sts per 4 inches / 10 cm).

yardage
Estimates are very approximate, since gauge can vary greatly within the same weight. Worsted will take around 350 yards; bulky around 500.

The pattern includes some more notes about estimating your yardage after section 1 to check if you’ll have enough to last to the end, gauge, using multiple colors, size proportions, measurements of the samples.

You can knit the sections in different colors if you want a multi-colored version. For yardage estimating, the first (bottom) section uses approximately 30% of the yardage, section 2 (middle) uses approx 27%, and section 3 (top) uses approx 43%, so plan accordingly.
