First, lie your Wrappr face down and place the spine of your book across the diagonal centre line of your wrap.
Grab the corner of the fabric nearest the length of the book, wrap it across the book and tuck any access fabric underneath the bottom of the book.
Then grab the corner of fabric near the bottom of the book and fold it on top.
With the remaining length of the wrap, fold it diagonally across the cover of the book.
I have quite a bit of excess fabric so I'm folding the wrap twice lengthwise.
Then rotate the book a bit so that you can easily grab each piece of remaining fabric with each hand.
And tie the two ends in a double knot.
And you're done!
