The 280-character limit for tweets on Twitter is double what it used to be, but it's still not enough to express thoughts in depth , ideas, comments, tirades, blogs, stories and the like. These tweet storms, as they are called, are the reason why Twitter created the thread function.
Threads allow you to quickly publish multiple tweets at once, all connected in a single stream, so your followers can easily read your fast tweet storms from one place. It is a great feature to discuss politics, prevent frustration, tell personal stories and dive into more nuanced topics.
Creating a thread is easy on your iPhone or Android phone, whether you use the full app, web app, or Twitter Lite, and it works just like it did in December 2017 when it was first released. You can all do the same things that you can do in regular solo tweets, such as adding images, links, videos & GIFs, so you are not limited in any way when creating a thread.
Create a Twitter thread  Log in to Twitter on your smartphone and then tap the new tweet button, the plus sign icon (+) and a goose feather. Unsubscribe your first tweet and add all desired links or media. Although almost everything is in threads, the only exception is when taking a photo with your camera, so that doesn't work here.
Once the first tweet of your new thread is ready, tap the plus sign (+) above the keyboard on the right to add a second. Then unsubscribe and add media to your second tweet in the thread. Keep doing this with as many tweets as needed.
Note: if you are done writing tweets but have added another one with the plus button, you can press the "X" button next to it to delete it. You can also go back and edit previous tweet drafts before you make it official.
