I kept hearing/seeing (on Facebook) people talk about pinterest recently and so, finally unable to bear the collective weight of the social media populace I went. It's really kind of awesome! Pictures of anything you want, and if you're crafty, it's heaven! So many awesome projects and decorations that I would fail miserably at if I tried.
But, the point! You can search pinterest for TLM stuff and it's great! Pictures and craft things, make-up and outfits inspired by the movie, not to mention pictures of babies dressed as mermaids. Nothing's better than that! There are a few things that are also on deviant art, but then again, there are some things that aren't. I highly recommend it to waste a few minutes when there's something much more important you should be doing. ;D
Here's the link but it changes all the time so I hope it works. If not, just go to pinterest.com and search for "The Little Mermaid".
