I'm new to this - just started knitting when I found out my friend is expecting twins. I'm trying to knit booties, but I keep getting stuck when the pattern says I need to add extra stitches.
I've been knitting, binding off various sections without a problem, but when I'm supposed to cast on additional stitches to a row I get stuck.
The bit I don't understand is that I only have the one, unknitted string to cast on with, rather than casting on at the start where you have a string either side of the needle.
Could somebody PLEASE explain how to do this.
