The really nice thing about this sort of built-in double knitted pocket is that there aren't any yarn ends to weave in or holes at top corners to snug up. See how tidy the back is even before finishing?
They're a larger version of the ones I used for Zora. Apart from their loveliness, their weight, or lack thereof, was a major factor in the decision. Nine buttons might really weigh down the front border, but these ones are hollow and light as a feather. Worth every penny.
While I had my camera out, I took this shot of the saddle shoulder.
What you see is the arm at the bottom and a bird's eye view of the the shoulder with the neck at the top. This smooth joining is all accomplished with a neat perpendicular join. No sewing required!
Finally, the yarn I used for this, Elann.com's Peruvian Highland Chunky, is a softly spun, non-superwash 2-ply, which unfortunately comes in small 50g balls. To avoid having to spend an eternity weaving in ends, I spit-spliced as much as possible.
