Welcome to the forum, John.
We get spoiled with frog-legged, pre-flattened cigar leaf from the Caribbean and Central America. It makes the world seem more orderly than it needs to be. And many cigar rolling videos seem to suggest that filler should start out flat, then be convoluted according to an orderly plan. Try just tearing the crumpled flojo into the length needed for the proposed cigar, and compressing it into a cylinder with your bare hands.
I've noticed that the frog-legging technique used with flojo is not as tidy as with leaf from most other regions. (I don't know if that is African or Paraguayan workmanship.) This results in some fairly hefty edges of central stem being present for the length of the leaf.
I would go with ChinaVoodoo here, and embrace the pre-crumpled flojo leaf. I do check it for stem chunks that might puncture my binder, but otherwise just use it without moisturizing further, and without un-crumpling it. It's got to end up scrunched into a cigar, regardless.
As a home grower, I am accustomed to rolling cigars from leaf that has been stored in tied hands. It's not flat, and doesn't benefit from flattening, unless I want to use it for binder or wrapper.
