Crafts: Vegetable Fabric Dyes

Here is something I'd really love to do once things settle down around here.  Read, after Pesach.  In the past the kids really enjoyed any project that required dying of any sort.  So this project from Whipup.net, fabric dying with vegetables,sounds like something we might really enjoy.  As an added bonus this is definitely educational, counts as science, one can mix history into this as well, because this is how fabrics were dyed once upon a time and it's frugal too, etc. I am really looking forward to this one.
