New to knitting, need to figure out needle size
I want to make a simple boat neck sweater ( just a few rectangles and sew them together, will be my first time knitting as a crocheter)
Will be using 80% cotton, 20% milk fiber 3ply ( recommended needle is 3mm)
But i want that flowy kind of fabric which doesnt have gaps but is still flowy and breathable. Which size needles should i use
