Update:
...and the bag is the pale brownish blob to the immediate right of the blue tail fluke. It'll look less like a blob when backstitched, but it doesn't show much in the completed pic, actually!
And I finished the rest of that side border after I took the pic.
And thanks for the nice comments, everyone - on both the pic and the kitten!

She is six months old, now, and has finally realised that she CAN jump high enough to get onto the kitchen worktops...
