Nice design!!! Are you planning on having the thin white outline in your design? I think you could do this using Batik method. You could start out with white material & pencil your designs onto individual squares (or rectangles) of material to be sewn together later. That way if one turns out good & maybe one doesn't, you wouldn't have to redo as many. You would start with waxing your thin white line & then dip in the salmon dye & air dry or cool setting on hair dryer & then wax the salmon color background & then dip in a brown dye for the final color. Then dry & iron out the wax. Voila!
