This is an advanced beginner / intermediate raglan quarter zip, knit in stockinette stitch. The yoke is worked first, including German Short Rows, and then the arms are separated from the body. The collar is worked back and forth while the body and arms are worked in the round. Stitches are picked up at the collar to create a backing for the zip. A zip is then sewn in.
This pattern includes 20 cm of positive ease. For a less oversized fit, consider using finer yarn or sizing down.
