Hi! I've just started learning crochet yesterday through visiting websites.

I am trying to make a scarf, but i'm stuck on the 3rd row!

I am having problems understanding this instruction.
sc in next ch-2 sp
I know that "sp" means "space". I tried researching on the net but have no luck whatsoever about what "space" is. So i know this may be silly, but could someone please help me with what this is.
