I always LOVE Doodlebug's booth. It's always bright and cheerful.
Simple Stories' booth is full of ideas and inspiration with layouts, cards, projects...I love that and take a bunch of pictures in their booth.
I love that Jillibean's booth is always the same and that they have some fantastic designers that use their products that make me buy more than I budget for.
Bella Blvd is another one that I really like. Again, bright and cheerful with TONS of ideas to take pictures of.
I'm not a huge Graphic 45 fan, but their booth is always fantastic. Their DT is amazing and they really do some cool things with their papers, etc. I can't seem to work with their paper, it's just not my style, but I can appreciate their beauty roaming around their booth.
