I didn't have rubber cement (because apparently it evaporates from the bottle?) so I used masking fluid instead, applied with a Clarity stencil brush, and my results were not quite as clean as they could have been. I spritzed the panel first with a yellow ColorBox Spritzer and brushed it out to even out the color. I added the masking fluid and let it dry and then spritzed again with orange, and brushed it out for a gradient effect. I did a little background stamping with the masking fluid still on, then rubbed it off to let the yellow background show through. So fun!
