I saw it on Deena's blog Eclectic Meanderings. Deena saw it on Gerdiary. How is happens, I don't know, but if you boil some white cloth in a pot with avocado skins & pits - you get pink fabric! Not being one to shrink from trying new things, I made some guacamole for lunch and popped the remains in a pot and let it simmer for a hour. Then I let it sit overnight.
The next morning...
Voila! Pink fabric!
Here it is drying on the porch rail. I have a feeling that there might be more avocados in my future.
