I had no idea that this could be done! I came across a post on The Babywearer with this title about a week ago. When I read the post, I saw a pretty, pretty pic of an ergo that had been hand dyed and "pimped." How fun! If you're "carrier crazy" you might want to check out her website: http://www.pimpmycarrier.com/ and peruse some of her handiwork. She does soft structured carriers and mei tais.
