I have another question (please forgive me if I'm annoying you!). Do you sew them up once they're rolled (so they stay rolled)? Or do you tie a string to them to make them easier to remove? Or do you just sort of shove the rolled up strip inside and then pull it out (where I would assume it became unrolled as it's removed?)

I think this is a really great idea. I've got a friend who doesn't like that she uses disposable products, but she really _likes_ tampons and doesn't want to switch to a sponge, cup, or cloth pads. I am going to mention this to her.
