Tap the Stickers button at the top of the screen (it looks like a folded sticky note, to the left of the “T”). Swipe left and right on the list to see the different categories. Scroll down to see the selection. Tapping an emoji will add it to the picture, and then you can drag it to exactly where you want it with your finger. You can add as many stickers as you'd like. Pinch to shrink, zoom to enlarge them. You can also rotate the sticker by placing your two fingers at the ends and rotating them at the same time. When you press and hold a sticker on a video Snap, the video will pause, allowing you to drag the sticker onto an object in the frame. Releasing the sticker on this object will "pin" it, and the sticker will track the object as it moves on the screen. Select a sticker. Zoom in on the sticker so that it completely loses shape, and put the focus on the edge of the emoji or sticker. The translucent edge can act as a custom color filter for your photo or video. Tap the scissors icon at the top of the screen, then use your finger to outline any part of the video, such a person's face. Now you've created a sticker that you can move to any place on the screen with your finger.  Stickers you make will appear at the top of the Stickers menu when you tap the Sticky-Note icon. You can remove the sticker from your image by holding and dragging it up toward the Sticky-Note icon, which will morph into a Trashcan as you approach.
