The cardigan is knitted from the bottom up in one piece until the armholes, when it’s divided into back piece and front pieces which are finished separately.
The sleeves are knitted back and forth and are finished off by being sewn onto the bodice.
Front bands and neck band are worked after all.

I added a small tutorial that I did not include in my pattern, because the cotton yarn that I used is not suitable for
this method and I did not want the cardigans that will be knitted according to my pattern to be damaged. But
because of your questions, I will try to write, as I did.
