Knitting Instructions For Scarves Having Trouble With Knitting Instructions?

Having trouble with knitting instructions? - knitting instructions for scarves

I'm trying to build boot of a book, and the statement that I am in number 15 piece says SKP 1 contact. What is the trick? Almost everything I've knitted hats and scarves were none, so I do not hope for me out of my tent, to find these boots.
Thanks for the help!
