Kimono Poncho...err I mean Cabled Cardi

I found this picture online for an awesome poncho but sadly the pattern was in Japanese and it looks a little small so I'm recreating it so I can knit one myself.

So far this is what I have planned out.

K2 P2 for 12 Rows

EDIT:

As of December 10, 2014 this has become a cardigan the stitches are the same but now this will have real sleeves.  I didn't think it was practical so I swapped it up a little bit.

Now I changed it around so it's now split the sleeves at 20 inches casted off 40 stitches on the RS and cast on 40 stitches on the WS.  When I get to the sleeves this is what needs to be done.

Pick up and knit 2 sts at the center armpit gap, working into the piece two rows below the edge, and pm between them. 46 [50, 54, 62, 68, 74, 82] sts
Work in St st for approx 2 inches.

Dec Rnd: Ssk, knit to last 2 sts, k2tog. 2 sts dec.
Rep Dec Rnd every 12 rnds until sleeve measures 17 inches or 2 inches shorter than desired length.

Change to smaller needles. Work 2 inches in K1 P1 rib and BO in patt.
Rep with other sleeve.
