When Is A Curve Not A Curve? Quilted Wall Hanging(4)

When Is A Curve Not A Curve?   The answer:  when it is a hyperbolic paraboloid.  What may look like a curve are in fact straight lines.  

This wall hanging was made using the Foundation Paper Piecing technique.

The wall hanging measures approximately 22 1/2 x 22 1/2" or 57 cms x  57  cms.  

On the back are four corners so that a piece of batten can be inserted (not provided).  The wall hanging may be hung in one of four ways.
