Cast on 96 stitches.
Knit garter stitch for 4 rounds. Then insert markers every 24 sts.
at 4" of length, decrease 1 st on the right side of each marker (92 sts).
Then every 2 inches, decrease one stitch at the marker alternating decreases on the left of the marker with decreases on the right of the marker for a total of 6 decreases. (88, 84, 80, 76, 72 sts).
With the decreases alternating on the right or left of the markers, it will prevent a vertical line of decreases.
Then knit another inch to 15" of length before binding off.

I think the purpose is to decrease in a more random way, as opposed to creating vertical decrease lines down the garment, which would have distracted from the texture and shape.
After the casting off and tidying up the ends, time for that finishing touch.
Brushing the stocking stitch to improve the nap makes for super cuddly, especially when there is a lovely, toasty young woman inside.
