PLEASE HELP! Double-stranding

Hi! I’m a beginning knitter and I’m making a scarf for my mom for christmas. The pattern that I’m using says I should use two strands of yarn from the same skein, one from the outside and one from the inside. The problem is, I can’t find the inside end. Can someone please help me?? Thank you!

It’s inside. Reach your fingers inside the skein and pinch. You may pull out a whole bunch, but just wind that up in a ball and you’ll be set.
