Lay books in center of scarf, pointing to the corner.
Take the corners on the left and right of the books and right a simple knot.
Grab the other two ends and pull up to position books into the middle.
I like to tie a double knot at the end to make sure I don't lose my books off my shoulder.
Then flip the book supporting corners on each side and carry. It's simple,cute and has a million functions. Hope you Enjoy.
