Gauge & Tension Calibration

Standard Swatch: 20 sc x 22 rows = 4 inches (10 cm) using Single Crochet (sc) in rows with your designated 3.5 mm (US E/4) hook.

Consistent firm tension prevents stuffing show-through.

Important Pattern Notes

  • Strict 3.5mm Hook Consistency: Maintain standard 3.5mm hook for all whale panels, fins, and tail flukes.
  • Tapered Tail Construction: Rows decrease gradually toward the caudal peduncle before flaring into swimming tail flukes.
  • Underbelly Texture: The cream underbelly panel incorporates front-post or ribbed row valleys to emulate baleen whale grooves.
  • Turning Chains: Ch 1 does not count as a stitch.
  • Stuffing: Stuff the broad forehead dome firmly while tapering stuffing lightly near the tail flukes for natural aquatic swimming motion.
