The website
Collections
Gather models into collections of your own, follow other people's, and browse every public one.
Save to a collection
Save on a model's page puts it in your Favourites, or in a collection of yours: make a new one there and then. Your collections are on your profile under Saved. A collection is public or private; a private one is yours alone.
A collection's page
Each public collection has a page at /c/<id>, with the site's header and footer: its cover, its name, its owner, its models as cards, Follow, and Share, which opens the sheet a model's page has with the collection's link. Following a collection puts each model added to it in your feed. A model's page says how many collections it is in.
The directory
brickworks.diy/collections, the gallery's Collections tab, lists every public collection as a card with its cover, name, owner, model count and Follow, newest first or most followed. The gallery's search finds one by its name, its description or its owner. It is linked from the footer too.
