How about a finished 6" block of the butterfly with a 4 patch block out of the blue and purple. This would showcase the butterfly then make a diagonal pattern of the two colors. Probably not painting a good word picture but you could scan the fabrics into EQ7 and make a mock-up of the pattern using a 4 patch block and a plain block. I have used this type of pattern for showcasing embroidery designs on plain block.
