This funnel series is meant to be used as a semitransparency: it has both front and back segments of the funnels, which means you can move objects through the funnel and still be visible. Layering and alignments are important with this series. The tutorial will advise you about how to use and format the funnels. There is another funnel series (FR001), that is not meant to be semitransparent. Be sure you choose the series that best suits your needs. Also, take a look at FR013 and FR029 and TO042 they are cut into two and three vertical cuts and TO042 has screens between the sections. They work perfectly with this series, making it easy to mix and match segments between the three series.
