Step 3: Turn Around
After wrapping the very last peg on the the top row, pull the yarn straight down between the two last pegs on the bottom row.
Wrap the yarn counter-clockwise around the last peg on the bottom row.
Pull the yarn up and wrap it clockwise around the last peg on the top row that does not have yarn on it.
Continue wrapping clockwise on the top and counter-clockwise on the bottom until you get to the left-hand end of the loom.
This completes a single row.
