For this scarecrow, a complete pattern would typically include something like:
Yarn: (brand, weight, and colors used)
Hook: e.g., 2.5 mm, 3.0 mm.
Stuffing
Yarn needle
Safety eyes (if used)
Finished size: e.g., 15 cm / 6 in tall
DK (light worsted) yarn → 3.0 mm hook
Worsted/aran yarn → 3.5 mm hook
Crochet tightly enough that stuffing won’t show through the stitches.
