You can use the colors or the image or both for your project. Here is a card I made.
The image is from the Big Boys Toys called Harley and the sentiment is Thinking of You.
Your project needs to use the Inspiration pictured above. We look forward to seeing what you will do with the challenge. You don't have to use Repeat Impression stamps but if you do, your name will be entered twice (2x) for a random drawing for a really nice gift certificate from Repeat Impressions. Check out Wendy's blog, The House That Stamps Built for the complete guidelines and link your project there.
You might want to check out what these Rock Star Designers have created to inspire you. Good luck - and I'm looking forward to seeing your projects.
Thanks for looking at my card - have a HAPPY stamping day.
