Hello, I am new to knitting and so far I'm loving it. I need help with something, though. I have some Bernat Satin yarn, which I love, it is so soft and silky, etc.
Anyway the suggested needle size is 5.0 mm / US 8 needles. I wish to knit a scarf with two strands of yarn together. Any idea on what size needle I should use, and is there a formula for determining this?
