If memory serves me right...(That is asking a lot!)
Take a picture of what you want, photo-copy it.
Take copy of pic and double-sided fusible web, using a lite-box or sunny window, trace the outline of the pic (the part you want black) onto fusible web,
iron web to black fabric,
cut out outline,
layout on background fabric, iron in place. I would sew around silhouette.
I did this for cat stairway to heaven quilt years ago and it has held up fine.
I hope I made that easy to follow.
