A bolt of white ribbon got rained on and I thought it was ruined, but being frugal, I ran water over it to clean it off. I then dropped red and green food color on both edges of the rolled up wet ribbon. I unrolled the ribbon and hung it up to dry. My colored hands were back to normal the next day, LOL. When it dried, I rewound the ribbon on an empty pill bottle. It is good as new. Here's a picture of how it turned out.
