Here are two t-shirts I stenciled hazard signs on. Actually ones a tank top but that's not the point.... I did this by printing the picture out then ironing the piece of paper onto a garbage bag then cutting it out and then ironing the stencil, plastic side down, onto the shirts. Then I painted it with acrylic paint!
