Facebook- how do I see them on my newsfeed again?

[L_A]

I made it so I wouldn't see someone on my newsfeed ('only important' or whatever it is) so now I never ever see their updates at all (unless i go on their profile).

How do I reverse that??

Because as they never come up on my newsfeed I can't select the little downwards arrow that is in the upper right corner of their post.

So how do I change it so that I can see them on my newsfeed again?

Thank you so much in advance!!
