Model was knit in Madelinetosh Tosh Merino Light in Candlewick
Stitch markers (optional)
Yarn over (yo)
Knit front & back (kfb)
I-cord bind off
This is a great website with videos on these and other stitches.
Cast on 3 stitches on size 6 needle
Row 1 (RS): kfb all (6 stitches)
Row 2 (WS): p all (6 stitches)
Row 3 (RS): k1, kfb, k1, kfb, kfb, k1 (9 stitches)
Row 4 (WS): k3, p6, k3
Row 5 (RS): k3, yo, k1, yo, k1, yo, k1, yo, k3 **Note: the pink stitch is the center stitch, you may want to use stitch markers to keep track of it**
Row 6 (WS): k all
Body Row 1 (RS): k3, yo, k to center stitch, yo, k1, yo, knit to last 3 stitches, yo, k3
Body Row 2 (WS): k3, p to last three stitches, k3
Every sixth row, knit a body ridge row:
Body ridge row (WS): k to center stitch, p1, k all
It can be tedious to count your rows like this, so it might be easier to keep an eye on the ridged edges of the wrong-side rows. There will be two rows with ridged edges between each body ridge row.
Repeat body rows 1 & 2 (keeping track of the ridge rows) until your 20th body ridge row.
Row 1 (RS): Purl all stitches
Row 2 (WS): Knit all stitches
Repeat edge rows 5 times (or as long as you like) ending on row 2
Bind off using a 3 stitch I-Cord bind off.
Cast on three stitches, k2, k2togtbl. Slide these three stitches back onto the left hand needle, then *k2, k2togtbl*. Repeat until the end of the row.
This is a great tutorial for the i-cord bind off.
Block as you like; I pinned mine into points a bit.
