Courses vs. Clubs
The "Courses" contain a finite number of pre-recorded lessons.
"Clubs" are infinite in that members receive access to a curriculum to follow AND an enormous library of courses.
There is also regularly released new content (both pre-recorded AND live) along with other member-exclusive perks including monthly giveaways, discounts on Etsy, regular live sessions, free admittance to online art parties, many free eBooks and more!
NOTE: The HUGE collection of many, many courses (classrooms based on art supply or theme) within each Club is NOT available for separate purchase elsewhere.
