[kuh-lek-shuhn]: a group of objects or an amount of material accumulated in one location.
Use collections to bring users and sketches together to share and create conversation.
Each collection is visible to public. It is administered by the creator, and any user may submit sketches to open collections.
Like the collections and sets in Flickr, but also somewhat a wiki; anyone can submit any sketch (if set), so that we can collaboratively bring these awesome sketches together.
or browse any collections below to see if there is already one that you want to contribute.
