Crochet pattern for the Cirrus children's jacket

With this sheet, you will be able to crochet this jacket made from Duvet d'Anjou (70% wool, 30% angora rabbit). 
We make granny squares with hearts of different colors, which we assemble together as we go. 
Then, we bring the shoulders together and crochet the sides. 
We make the side seams. 
The jacket is either long sleeved, crocheted in the round, or sleeveless with dropped shoulders, with a crochet border. 
The edges of the lower body and neckline are also made with crochet ribbing.
 It is available from 4 to 12 years old. 
For material, you will need hook 4.5 and a round-tipped wool needle.   This pattern is printed in A4 format and presented in a transparent pocket. 
In addition to the explanations for making the model, find advice and tips on knitting finishes, the composition and maintenance of wool, etc.
