Instagram Stories, the Snapchat-inspired feature that Instagram has been upgrading at an accelerated pace—and which is now used by 200 million people a day—is getting some new sticker-related features. You can now turn a selfie into a sticker. And (as in Snapchat Stories) you can "pin" a sticker to a particular spot in a video, such as someone's shirt, whereupon it will travel along as that spot moves.
In addition, Stories is adding geo-stickers—stickers that are available only when you're in a particular area—for Chicago, London, Madrid, and Tokyo. Each city's stickers were designed by locals.
