As a homeschool project last year my son grew some natural colored cotton (brown and green). Very cool!!! Not only are the plants very pretty on their on, but you can grow your own cotton balls. LOL I was going to try spinning it but ... :gaah: I wanted to get the wool done first. But I will get there ... sooner or later. (now looks like later) I think I will try the red cotton next ... Here is a little info on the revival of colored cotton ... The Revival of Colored Cotton, James M. Vreeland, Jr.
