This is my first pattern to be published here on Ravelry. Using the gorgeous Amitola yarn by Louise Harding, however, any self striping yarn will work well, Schoppel Wolle Zauberball or Noro.
It is named after the beautiful river in Wales that flows past my family home in Wales.
Guage is not important for this pattern, just make sure the needles you use create a nice drape.

4.5mm needles

Abbreviations
pm = place marker
sm = slip marker
yo = yarn over
k2tog = knit 2 together
RS = right side
WS = wrong side
RN - right needle
LN - left needle

Start here
Cast on 3, knit 6 rows, at the end of the last row, do not turn your work, but pick up and knit 3 stitches along the side of your garter stitch tab, and 3 stitches along the cast on edge giving you 9 stitches in total.

Now follow this simple repeat alternating between the two balls of yarn every two rows:

1. k3, pm, yo, k1, yo, pm, k1, pm, yo, k1, yo, pm, k3
2. k3, sm, purl to last 3 sts, sm, k3
3. k3, sm, yo, k to first marker, yo, sm, k1, sm, yo knit to next marker, yo, sm, k3
4. k3, sm, purl to last 3 sts, sm, k3

Repeat rows 3 and 4 for as long as you like, this forms the basis of the triangle shawl.

The eyelet rows are made by keeping the k3, yo at the start followed by k2tog, yo repeated across the row to the centre, yo, sm, yo (for the middle) the continue K2tog, yo to the last 3 stitches, sm knit 3.

You can choose to do this once or repeated on RS rows whilst keeping WS rows as row 4.

Finally, I used a picot cast off (make sure you leave yourself enough yarn as it uses approximately 3 times as much yarn as a standard cast off.

Picot cast off - cast on 2 stitches, cast off 3 stitches, put the stitch on the RN back onto the LN and repeat from. There is a great you tube tutorial to help with this
