The design is made by Lillith for her tiny dolls (lillim.com).
I have created this pattern for her from that design.

This is a long cardigan in double crochet (us) with decoration lines in Front Post Double Crochet and Back Post Double Crochet.

The cardigan is created for tiny bjd dolls from lillim.com, but will also fit Mascat 26 line and other dolls of similar size.

The cardigan measures:
Sleeve length from neck to hand - 10 cm
Cardigan length from neck to bottom edge - 12 cm
Cardigan width at waist - 12 cm
Cardigan width at bottom edge - 22 cm

It is always a challenge to crochet small sleeves like this, but the rest of the cardigan is quite straight forward for most crocheters.

Good Luck!
