I wanted to post another forum I have come across which has a section for questions on dyeing:
www.craftster.org/forum/index.php?board=327.0. There are probably other threads at this site that deal with dyeing, but I saw several topics listed here that were intriguing. I would also like to mention that a search on youtube for tie-dye will result in a lot of video on techniques! Technology has opened up a whole new world of information that is readily available to us for learning new (to us) ways of folding and dyeing, discharging, etc. It's worth spending a little time to see what is out there.
