Chibi doll Nana is about 14 cm (5.5 inches) tall without ears.
I used small ply balinese cotton yarn (8 ply sport yarn) and Tulip hook no. 2/0 (2 mm hook).
Boomerang height is about 11.5 cm (4.5 inches).

Used stitches:
ch = chain
sc = single crochet
hdc = half double crochet
inc = single crochet increase (2 sc in next st)
dec = single crochet decrease (join next 2 sts into 1)
FLO = front loop only
BLO = back loop only
sl st = slip stitch
