I really like the coffee mug image - it comes from the series called Pairings. It is a series of large and small images and sentiments. The sentiment is actually two - Thinking of.... is one from the Quartet Compliments and the You is from the new large sentiments series.
Here is the list of Rock Star Designers who have made something to inspire you for this challenge. You don't have to use Repeat Impression stamps but if you do, you 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. Good luck - and I'm looking forward to see your projects.
Have a Happy Stamping Day!
