hey there! don’t worry about your follower size, everyone starts of in the same place and trust me, on my own account i had that number for months. 

my best advice from personal experience would be:

follow accounts and make friends with fellow stranger things fans.

keep you blog active (if you’re busy, try setting up a queue).

present your blog nicely: choose a simple and basic theme that also can make your blog unique. you can find so many themes here.

if you can, make edits and gifsets of the tv shows and films that you love. that always grabs a lot of users attention. if you’re not sure how to do any of that, there are plenty of tutorials via @itsphotoshop and i myself have made a tutorial here.

also it never hurts to ask a blog for a shoutout. there will be some who reject you, but i always think it’s worth asking as the worst outcome is that they will say no.

i wish you all the best on your blog and i hope you are able to build your blog into something that not only celebrates your love for the show, but that celebrates your personality and interests. also i hope you and your family have a wonderful new year and thank you so much for all your love for the blog, it is really appreciated!
