I started out by laying my stencil over a piece of watercolour paper. I sprinkled two shades of red brushos over the openings in the stencil, spritzed with water, and quickly removed the stencil. When it was dry, I stamped and heat embossed my sentiment. The watercolour panel is popped up on fun foam for some dimension.
