Moonpi suggestions are far more creative than anything I can think of. If you are like me, and don't enjoy paper piecing, and still want to use this idea, you could get a fabric maybe with large flowers in ti and not have to worry about piecing or applique. Just fussy cut the block centered around the flower.
Or just cut the flower out and fuse it to your background. I can send you a pkg of fine fuse and a pressing sheet if that method interests you. All that you need to do after that is topstitch the piece to the background--just straight stitching.
