This botanical blue fern print is a cyanotype, i.e. a "sun print", which is an actual photographic image made by using the power of the sun on specially treated fabric.
This is a photographic image of a fern I made on a sunny afternoon last fall with one of my garden ferns. It's on an 8 1\/2" cotton fabric square.
What to do with it? If I were patient enough to sew I would make a pillow, a quilting square, or even a wall hanging, but a sewer I'm not! If you are, it's available on my Etsy shop.
