First, Welcome!

Second, Get rid of the plastic bag!!!

Jades do not need humidity or excess moisture!

Don't water the cuttings, either. If you watered the mix already, I'd remove the
cuttings, examine for rot, and then re-pot.

Thanks Josh!
I removed the bag and pulled out the two cuttings. While the large one seemed to have a little rot, the smaller one (lo and behold) had a tiny root. Some follow up questions:
I'm assuming, following the new cut, that I should let the stems dry out again for a week or so, right? And second, what type of sunlight would you suggest once you pot them? The jade guy at our farmers market told me that jades love direct sunlight, but I'm guessing it's best to ease them into it. I planted my new cutting into a mixture of gravel and soil until I can get my stuff together and actually buy some sort of cactus/succulent soil. In the meantime, things are looking pretty good.
Thanks again.

You can dry the cut for anywhere between a few days to a few weeks, so long as a callous forms. I have tossed freshly cut leaves and branches straight into a pot of dirt and have had no problems. The important thing is to insert the cutting into dry soil. You can mist the leaves gently every few days to prevent excessive drying, but you don't have to.

They'll root perfectly fine in normal potting medium, just be sure to transfer them into a coarse, well draining mixture once the roots are established.

The cuttings would do best out of direct sunlight and in filtered light or shade. You don't want excessive heat drying out the cuttings too much at this point. It won't necessarily kill them, but it may slow down rooting.

Jades are tough and very hard to kill short of overwatering.
They'll root perfectly fine pretty much regardless of what you do to them so long as you do not water until some roots are established.

To let the cuttings callous over is never a bad idea..I just rest mine in dry sand or soil and sand or just bark and they just root on their own..

Once they are planted and ready to start growing, full sun is always appreciated by them.. They will tolerate indirect sun, but grow much more compact in full sun..
