I would like to try this challenge too! I just bought a small house, so I need to use up my stash and organize as well.
For inspiration, I also recommend the card sketches/gallery here on SCS and using Becky Fleck's Card Maps. In the past, I've also looked at 365cards.blogspot.com, and because I love Oriental Stamp Art, I check out osadesignchallenges.wordpress.com. Hope that helps someone else too.
Happy stamping, y'all!
