A seaming party, that is:
They yarn is Meilenweit Cotton Fantasy, color 815. The pattern is from The Essential Baby Book by Hayfield that I picked up in a used book store.
And here's a quick tip for those who hold the yarn in their right hands: When casting off on the wrong side row, you can easily duplicate the look of the standard cast off (k1 slip the last stitch knit over this stitch) by using the decrease cast off (p2tog, slip the new stitch back onto the left needle). The decrease on the wrong side looks exactly like the standard on the right side. No more flipping the yarn front and back to cast off on the purl side!
