What is Patreon? Patreon is a membership platform that makes it easy for creators to get financial support. Patreon is a way to join your favorite creator’s community and pay them for making the stuff you love. Instead of literally throwing money at your screen (trust us, that doesn’t work), you can now pay a few bucks per month or per post that a creator makes.  For example, if you pay €2 per video, and the creator releases 3 videos in February, then your card gets charged a total of €6 that month.  This means the creator gets paid regularly (every time she releases something new), and you become a bonafide, real-life patron of the arts.  That’s right–Imagine you, in a long frilly white wig, painted on a 10-foot canvas on the wall of a Victorian mansion.  And imagine your favorite creators making a living doing what they do best… because of you.
