Landscape quilt - large area without quilting
I'm doing a landscape quilt from a photo that has a perfectly blue clear sky. I would like to not have any quilting in the sky area because I don't want to take away the look of that clear, clear sky. Would anyone have a suggestion about how I can get the sky fabric so that it will remain smooth, and not have wrinkles in it. The sky area is about 30" wide x 9 " high. I was thinking about fusing something to it, but I'm not sure what would work best.
Thanks for any advice!
