We set them out in shopping bags, and they grew well as you can see from the following pictures:
Then it got cold and the tops died off. So we dumped them out (sorry we did it on a whim and I forgot to get pictures) and found....
that they needed a little longer. Tubers did grow but didn't have time to fully reach potato status. Now I wish we had left one in to see if they'd continue growing or not. I don't think they would have and wish I had remembered to cover them before it got cold. If I had maybe they would have had time to male a more substantial tuber. Also, if we'd had a typical (warmer) November they might have had more time.
It wasn't a success, but does let me know we can plant on sale plants later than usual but probably not as late as we did and that they do grow well in shopping bags. I would pick a thick strong bag. Our smaller and stronger bag can be used again but the larger one just tore to pieces.
It is nice to have that area clear since it allowed us to put the side garden to bed. Look for a post about that soon. Happy gardening everyone!
