Welcome Stephen.
I find very tempting to manipulate the cuttings to see what they are doing, if roots are pushing out, etc, so I find that the bag is more trouble. I like a plastic container that has firm wall, you put the paper under and a criss cross with the cutting so there is air around them. and cover them with more paper, like a blanket and tuck them to sleep... Good luck and do share your experience. Lots of great fig members out in your part of the world. I am lucky to have a few of your NY figs growing here in the PNW.
