I've become a fan of stamp and die sets, which can be kind of expensive at times, so I'm always on the hunt for the best deals. Stampin Up sells my favorite sets but I also like Lawn Fawn, 7Gypsies, & Echo Park.
This Lawn Fawn card inspired me to create some A10 Birthday cards with the 'flying by' trailing behind the airplane.
For scrapbooking supplies, my favorites are October Afternoon and Graphic 45. These projects from the Graphic45 theme Voyage Beneath the Sea, especially this one, are some of the most beautiful I've ever seen and these have inspired me to buy each of the sets.
