Cheapo Dies is offering a $15 gift certificate,
which goes a long way.
For my card, I used soft cream to dark yellow tones.
This is a rather untraditional monochromatic yellow scene. While this is not a Cheapo Die, Cheapo Dies has a wonderful lighthouse scene for you to try.here as well as dotted rectangle dies here. I'm afraid the true colors of the panel that seems to be white with some red tones is not white, but is sponged fossilized amber. This is much prettier in person. But I hope this gives you an idea of using monochromatic colors.
