thank you all.  Yes, I know they are psp tubes that are shown, but I am looking for what would have been used to crete them to begin with - just the bow and ribbon parts, before being combined with other elements and being made into a 2D tube.

The person who runs this site uses Poser to create the bulk of her tubes.

I was hoping someone would know of a product for Poser and/or Daz Studio that creates bows like that, or something similar.

Thanks for the info on creating it with a plane.  I'll keep that in mind.
