I like the PVC pipe and hanging idea best, standing them in a closet second best. My experience with the vacuum bags has not been the best. They do wrinkle fabric, plus all of mine have deflated over time. You still have to store the bags, and they don't necessarily stack all that well once they are vacuumed. All of mine came with a strong plastic smell to them also. They would cost considerably more than a PVC pipe and some thrift store sheets too.
