This was a challenge done for Fourth Corner Quilt Shop in Bellingham in Summer 2009.  The requirements were that a recognizable amount of the challenge fabric had to be used and the outside dimensions had to be 8-1/2 x 11 inches.  The challenge fabric are the 2 spotted balloons and the binding.  It was the first and so far, only time I have attempted trapunto.  The balloons are supposed to be much puffier than they turned out to be. Learned a lot and will definitely be trying it again.
