You are right to show off the fabric in large pieces, that's worth an impulse buy.
I have a collection of fabrics and some ideas for a fantasy quilt. This would fit right in with a lot of my fabric in colors and would be lovely as long columns between columns of pieced blocks. Whether pictorial through paper piecing or simply made of the fantasy fabrics... hmm... mental designer active...
Similarly, as a wide border with the interior of the quilt some sort of star/floral shape blocks of the colors from the fabric.
