I love tea dyed fabrics! But you might want to try dyeing scraps of each fabric first, so you know how it will turn out. It would be a shame to dye the finished outfits and then find out that some parts look better than others. You could also get the same effect using fabric in muted colors and using beige or cream fabric and ribbon instead of white for pinafores, slips and bloomers.

I have to go to my studio now, you've got my creative juices running, thanks, Phyllis!
