Learn how to share Instagram posts as your Story.
Instagram does not let you repost others posts, but it lets you use posts as stories. That’s because it need as more Stories as possible, to put ads between them.
Anyhow, the point is that you can make your own stories from Instagram posts.
When you find a post you like and want to share as a Story, just tap the share button under it (net to the comments button).
Then choose Add Post to Your Story from the menu.
You can now make some modification of your own, like adding text or effects.
Finally, tap the Your Story button from the bottom right of the screen.
There you have it: your own Story from a post. You can also do this with your own posts.
