It was 3.5mm and it was too sticky ㅜㅜ I raised it up to 4 mm and 4.5 mm 😭 You have to write 4.5 millimeters to get the gauge right, but... The knitted fabric is 4mm clean and so pretty... I decided to write 4mm and increase the size...ㅠㅠLOL It feels like ready-made clothes when you make it when it's tight It's my first time opening an aran pattern, and as expected, a gauge is important for children with patterns. 이렇게 I learned it like this...😉
