With this pattern you will be able to make THREE cardigans for a baby girl age from 0 months to 2 years. The instructions contain several videos and multiple photos that would allow you to learn how to make this particular model and even create your own based on this design.
Depending on the size, you will need anywhere from 100 gr to 300 gr of yarn plus up to 50 gr of two additional colors yarn to create the flowery design. I used the crochet hook #3.5, but it all depends on what yarn you going to use. This can be a summer raglan or a winter cardigan. If you need recommendations on the yarn or anything else, please, contact me and I will be happy to give you more personalized instructions.
Have fun with this project! Your baby girl will look stunning in this dress!
