How to dye paper doilies with red wine. These are regular paper doilies dyed in Merlot! The color intensity varies depending on how long you leave them soak in wine. If you have doilies from different vendors, you will have to try them first. Some do not resist more than 10 seconds and others can be left soaking overnight. if you use wine, 10 minutes is long enough. if you use coffee, it can take 2 hours to get a mild creme color. Good luck!
