Question 733907
Hint: 


Step 1) Start with a 9" by 11" piece of paper


Step 2) Add circles of radius 3 to each corner like you see below


Step 3) Cut off the corner bits of the rectangle that are outside of the circle


Step 4) Erase the circles and you have your basic shape/outline of the paper. This is the path that the ribbon will take.
