When I cut the portrait of my nephew and his fiance, I cut a stack of 3. The top and center cuts are mounted on black painted BB Ply. The 3rd cut I used as a stencil to spray fabric paint on 2 t-shirts for the bride and groom. I wanted to paint on pillow cases but the wife nixed that idea.
Anyway, here's how they came out. I used midnight black fabric spray paint from Hobby Lobby, but it came out more like a charcoal gray. I may go back and cut in some text, but my sister wanted the framed version w/o any wording, so that's the stencil so far.
