It was originally her idea to film propos on a stage with a script for Katniss to read. However, it was a total flop because Katniss didn't come across well unless she was being herself, not what others wanted her to be. Fulvia's pride is wounded when Haymitch Abernathy comes up with a better plan to put her out where the real action is and film her when she is being herself.
Later, Fulvia redeems herself by coming up with the idea of doing a montage of propos dedicated to the fallen tributes of the districts, such as Rue or Mags. They would contain commentary from Finnick Odair with the theme being "We Remember," read out by Claudius Templesmith. This would then appeal to the people of the districts on a closer level since many of them would have had personal feelings towards their own tributes.
Fulvia is one of the few named rebels that survived the rebellion.
In Mockingjay, Katniss mentions that she has silver flowers tattooed onto her plump cheeks, however she does not have many of the standard Capitol traits as she moved to District 13.
