The reverse loom: the person in the middle gives first, then the circle gives back.
Check back soon. A new loom opens as soon as the next one is ready.
The member in the center signs up through the app in every seat around them. Each sign-up has to be a real account.
Once the center has blessed every seat, the circle turns around and sends traffic, views and sign-ups back to the center.
The center moves on and the next member takes the middle seat. Likes, comments and shares are welcome but never required.
