If you are trying to transfer the designs to the other fabric you might need to look into another method. How about finding a rubber dolphin stamp and printing it on the fabric? If you want an exact duplicate, I would trace the image with my light box. Transfer the outline of the image to freezer paper on the paper side. Cut out the image outline ( leave little connecting pieces) and iron it to the fabric you want to print. Use a permanent paint to stencil the image.
