This cardigan comes in 10 sizes, all written separately. The body is worked in one piece starting from the bottom back. The sleeves are made in joined rounds and the sides are seamed.

This pattern uses the same stitch in the sunflower overalls / dress that I also sell the pattern for in another listing, pictures of the cardigan with the sunflower overalls / dress in photos.

The pattern is beginner friendly, made using a simple single and double crochet (suzette stitch). The pattern also contains plenty of photos and a video for the sleeves and seaming.
