This is an easy t-shirt to knit. It’s a nice project for beginners. The yarn I used is Rauma Pelini, but any cotton yarn with a gauge of 20st=10 cm will do just fine. You will need 4 to 6 skeins, depending on the size and length.
This t-shirt is knitted top-down. You start knitting back and forth to make the opening at the back, and then knit in rounds. The body and the sleeves are knitted separately.
