Left overs from cutting packages sent to my friends are kept for a while in the fridge and when Mrs. starts complaining for lack of space... wrap those bits and pieces of fig scions in a sheet of  wet newspaper then inside a plastic bag horizontaly,  and hang all that on a nail in the wall inside the washing room.
Occasionally, say once a week a couple of mouth sprays into the bag will keep humidity on an acceptable level.

Later on, other more demanding friends, say no to my suggestion of a couple of good fig scions and instead say.... if they were already rooted--?!
Right, for some of these special friends I disentangle ( warm water helps a lot)  a few of these cuttings
and pot them in 1Litre cups with a standard soil mix.

Love it!

They look lovely Francisco ,as far as untangling them,not to worry I'll take them all as they are! ;)

Nice!

Thank you for posting, gives me ideas to try. It looks like you had no mold issues.

Wow!  Look at those roots.  I am envious...

Thank you for commenting this 'fig root chaos' !
You may use a similar system although a bit more disciplined, wrapping the scions single or in pairs inside individual bags.  Mold is never an issue, and you see lots of roots before a leaf pops out. (just the other way around !!). No rooting boosters and/or hormones are used..just weekly tap water short sprays.
The temperature inside the room is 20 to 25ºC.. that wall faces W and radiates heat to the inside.
Once taken out of the bag and potted on a more or less rich media, it grows very rapidly.
