The canna rhizome is rich in starch, and it has many uses in agriculture. All of the plant has commercial value, rhizomes for starch (consumption by humans and livestock), stems and foliage for animal fodder, young shoots as a vegetable and young seeds as an addition to tortillas. The seeds are used as beads in jewelry.[12] The seeds are used as the mobile elements of the kayamb, a musical instrument from Réunion, as well as the hosho, a gourd rattle from Zimbabwe, where the seeds are known as "hota" seeds. In more remote regions of India, cannas are fermented to produce alcohol.[13] The plant yields a fibre—from the stem—it is used as a jute substitute.[14] A fibre obtained from the leaves is used for making paper. The leaves are harvested in late summer after the plant has flowered, they are scraped to remove the outer skin and are then soaked in water for 2 hours prior to cooking. The fibres are cooked for 24 hours with lye and then beaten in a blender. They make a light tan brown paper.[14] A purple dye is obtained from the seed.[14] Smoke from the burning leaves is said to be insecticidal.[14] Cannas are used to extract many undesirable pollutants in a wetland environment as they have a high tolerance to contaminants.[15][16] In Thailand, Cannas are a traditional gift for Father's Day. In Vietnam, canna is called dong riềng and its starch is used to make cellophane noodles known as miến dong.

As a guy who makes toilet paper for a living, I can tell you that's a terrible idea. You need to stock up on several years supply.
It has been scientifically prove using toilet paper substitutes causes cellulite, irreversable brain damage, hair cancer, blindness, and hardening of the boogers.
Don't do it!
I've been buying hundreds of used bath/beach/dish towels at garage sales...for practically nothing. When the ladies ask what I'll do with them, I say, I use them in the shop to wipe oil etc. (and, I do that too, they're much cheaper that the 'rags' at Sam's).
LOL. I did freak one woman out when I said that I'd use them to soak up the blood on the floor of the operating room when the revolution starts. (I just did that once)
