I buy lots of prints in the artists' alley! A2 and A3 sizes are my favorite because I can put them on my wall like posters. It's mostly fan art, but if I really like the artist or their artwork looks cool, I sometimes buy ones of their original characters as well. Buttons are cute...I recently realized I could use them to decorate my school bags, so I've been buying some. I don't really buy bookmarks. I never really use them when I read. Stickers...I don't want to use them; they're too precious! So I don't buy many stickers. Plushies are so expensive. But oh artbooks for artists I already know are amazing...I would buy those. And yes, keychains and cell phone charms are awesome. I always buy those.
