Crowdfunding is the art of rallying your community to fund your project. 

Remember, not everyone you ask to give will give, so even a modest crowdfunding campaign aiming to raise a few thousand dollars requires getting in front of thousands of people.
Unless you’re famous in your own right or have strong social influence, it’s unlikely you’ve got immediate access to a network of this size. Here’s where PR comes to the party.

A stretch goal is an extension of your target, where you specify the extra funds required to get your art to the next level.

Social media is a handy marketing tool, but you don’t own your social media community. The visibility of your posts is at the mercy of social media algorithms. In other words, just because you publish a status update, doesn’t mean people see it. Furthermore, if the gods of digital decide to fold a platform, that’s your hard-earned followers gone in a blink.
