Are you not completely sure how to knit a Icelandic Sweater? Are you maybe a beginner or have you only knitted raglan sweatera before?
It is easier than you think to knit your own Icelanic sweater. Everything is knitted in a round and you never have to sew any parts together. You only need to sew the armholes together.
I have made a 25 minute long video and put it out on youtube on how to knit a Icelandic sweater. Enjoy!
