By changing the colors, your card can look very different, even when the same stamp set is being used. Take this card as an example. The Poppy ink and background color takes on a truer fall feeling than this card as Fern is the focal, and even this card with Saffron accents.
The rolling technique was used with Saffron and Poppy ink. Ink the leaf with Saffron ink, then roll the stamp's edges in Poppy ink, inking just the outside of the image. Then stamp the image on the paper. Make sure you stamp off the image before returning it to Saffron for another image so that the Poppy doesn't "stain" your Saffron ink pad.
Don't worry if it does, just grab a tissue and wipe the Poppy ink off of the Saffron inkpad.
Sapphire and Fern ink round out the colors used for this card. The saying is highlighted by mounting it with 3D Foam Tape and the Gold Sequins.
I could continue making these cards in different color combinations, but I have other projects to get to. Hopefully you see the versatility of your stamp sets, and that you can use them over and over - never getting bored by making the "same" thing again and again. : )
