I flipped the stamp back over and added the actual lemon slices in yellow.
Next, I used the "Yello!" die that comes with the set to cut out the sentiment on the circles. After mounting the front panel to the card, I die cut the sentiment again, and then added it to the negative space left on the card. I added some white details to it to help it stand out from the background. I stamped the lemon slice, colored it, and then cut it down to fit over the "o" in the sentiment.
Lastly, I added some faux washi tape strips and smaller white dots to bring more white to the front of the card.
I'm gonna brighten someone's day!
