Check out this
homemade toothpaste recipe. I didn't even know this was possible. Since I rarely buy toothpaste for more than a dollar a tube I don't know if this would be cheaper for me, but I thought it was blog worthy. Just fyi, if you want to try this you need to get the
liquid glycerin which they sell at CVS or Rite Aid (look in the cosmetics section), not the solid kind they use for soap.
