Dying already dyed yarn

On Ravelry, I have been admiring all the hand dyed yarns...and one of the members gave me a link to a great website, for dying store bought yarn and food colouring...so I am going to give it a go, I have a few odd balls of yarn, and a skein of white yarn that is damaged with either dirt or grease. So it might be good to give it a go and make my own skein of personal hand dyed yarn. ^_^

I have read through Pea Soup of the Day's blog, and it seems so simple and interesting! Now all I have to do is unwind the yarn, buy food colouring, and do it.
