I used the colors as my inspiration. Here is my card.
The images are Leaf Cluster Outline and Flower Cluster Solid with the Lady Slipper that was embossed in white. The background was sponged on using a variety of Tim Holtz inks. The sentiment, Vertical Thinking of You was embossed on vellum.
For me these challenges are always fun and 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.
