As the original yarn is no longer available, New Zealandsk Lammeuld by G-uld is a good alternative, and so is Holst Garn Supersoft.

For pattern support please go to the questions thread here.

update 11/21: correction in Spanish translation

Jingle is worked seamlessly from the top down. First some short rows are worked back and forth to create a higher back neck and then the yoke is worked top down, in the round, to sleeve separation. Some last short rows are worked to finish the yoke shaping right before sleeve stitches are placed on hold, then the body is worked in rounds down to the hem. Sleeves are worked top down to the cuffs last. No finishing required.

Note: At the testers request there is an option for a smaller neckline for sizes 3 - 10. Instructions for this can be found immediately following the original neckline.
