Nele, to allow me to copy paste your beautiful teenager sweater! I learned to use a new jersey stitch and loved it! And I changed it a bit into a dress.
The challenge of this project was to get it out of the available fabric. I bought it at MondaysMilk (check out their new Nani Iro's!) and since there was only 1,7 m left, did it take me one evening puzzling. The inside of the pockets ended up in a different fabric.
