If you want to post a fun Story, but you don’t want your random Instagram followers seeing it, try posting a Close Friends Story.
The Instagram feature Close Friends allows to you to post stories to a select group of your followers. With Close Friends you can choose to post a Story to all of your followers or to just to that designated group. No one else can see who is on your Close Friends list, but individual users know they are on the list because Close Friends Stories have a green circle around them rather than the usual pink and orange circle.
You can also edit your Close Friends list at anytime.
Here is how to post a close friends story.
