A collect is when a juggler stops juggling and catches all the objects. Rings are the easiest prop to collect. Doing a trick "to a collect" means collecting the objects immediately after doing the trick, rather than resuming the basic pattern or connecting to another trick. Ending a pattern with a collect is called a "clean finish".
