Because of the loose skin and fluffy coat, most of the haunches seem to meld into the body, only appearing as a slight bump on each side (plus the feet of course). To make sure these bumps will be at the right place, flatten the bunny side to side so that the eyes and front legs are symmetrical. Your last stitch should be 18 sc away from the fold at the bottom – add or remove stitches if necessary.
(this check is important because crochet has a natural tilt that might be slightly different for every crocheter)
