It took me over half an hour to work that top row, decreasing here, adding a bead there.
Click to embiggen. I measured across the top after having worked this row but before working the next, stabilizing, row: approximately 25cm. 193 stitches condensed to 91. Ribbing at the waist will remove another 7cm or so, or I could knit in darts. I’m setting this aside for a bit to work on something human-scale, and to ask Kurr for more measurements.
It will be ever so much easier to design for Cuprit, once she is here.
