Pick up an extra bag of cranberries this year and dye a set of napkins for Thanksgiving. Put white cotton napkins in a simmering pot of 8 cups water mixed with 1/2 cup salt for 1 hour (this will help seal the dye later). Meanwhile, simmer 2 cups each cranberries, cranberry juice and water for 30 minutes in another pot, mashing the cranberries; strain and return the liquid to the pot. Rinse the napkins in cold water, squeeze dry and leave one end in the cranberry liquid for 4 hours. Rinse again, squeeze and hang to dry.
