Yarn choice: Bamboospun, color brown I used about 3.5 skeins or just over 500 yards.
Needles: US 11
Gauge: Who cares?
Finished size: 38" x 38"
Cast on 4 stitches.
Row 1: K1, P1, K1, P1
Row 2: K1, P1, K1, YO, K1
Row 3: K1, P1, K1, YO, K1, P1
Row 4: K1, P1, K1, YO, K1, P1, K1
Row 5: K1, P1, K1, YO, K1, K1, P1, K1
Row 6: K1, P1, K1, YO, K1, P1, K1, P1, K1
So then from there, work seed stitch (K1, P1, K1) on the first 3 and last 3 stitches of each row. Yarn over once every row after the third stitch, then start with a knit stitch.
So row 7 would look like this:
Seed stitch 3, YO, K1, P1, K1, seed stitch 3
Basically, your middle section is a cross between a seed stitch and a moss stitch. The first and last 3 stitches are the border, so make sure you end with K1, P1, K1 or your one side will end up looking funny and won't match the other side. You are going to always start the middle section with a knit stitch. The middle section will end on a knit on the odd rows.
You can see how the pattern from the edge is different from the middle section here.
Continue to increase until blanket is as big as you want or you've worked half your yarn stash. Then work 2 rows without increasing in the pattern.
Then start to decrease like this:
Seed stitch first 3, YO, P2tog, K2tog, *P1, K1 (repeat from * to last 3 stitches), seed stitch last 3.
Bind off when you are left with 4 stitches.
