Knitting with two strands together

I am new to knitting and I’m going to try a baby blanket. The instructions say ‘with 2 strands of yarn held together, cast on 110 sts loosely’. This may seem obvious but how do you go about this? I need some clarifcation.:??

Take the ends of 2 skeins of yarn and hold them together and knit as if they are one.
Just remember as you work that you are using 2 strands or you may end up accidently making extra stitches.
