Arrange and share
Pinch to resize, rotate and drag each photo, then add text or stickers and share.
Design the Story as one image
The Stories editor is quick but loose: photos snap only roughly, and it is hard to repeat the same style next time. Designing the collage as one 9:16 image gives you exact spacing, cutouts, frames and type, and a look you can reuse.
Make a Story collage in Glassy

Choose a Story-size template, such as Summer Keepsakes, September Stories or Window Calendar.
Fill it with your photos
Tap Use template and select your photos; they fill the slots in the order you choose them.
