What I use
Chamomille ( ordinary type not the dyer kind)
White tea with blueberry and centaury leaf
Kukicha tea (another kind of green)
Matcha ( green tea in powder)
Rooibos ( red )
Black tea with roses
Here is how I did
I choose 11 teas or herbal tea I wish to try.I put 2 tablespoons of tea for those who are dark and up to 4 tablespoons for pale tea in 11 differents bowls.I use + - 1 cup and half of boiling water for each of them.In each I add a piece of the fabric I wish to use for the costume of my son , the goal being to find two matching colors .The fabric remain 45 min in each bath .After I remove the excess of water and let them dry.
I know some of you will ask why did I try instant coffee and some tea which will probably not work.Curiosity first and next because I didn't know anyone who ever try something like this.By trying something new we learn and I did learn a lot from this.The experience is not 100% perfect but it's find for me.
Chamomille did not change a lot.Just enough to say it's not pure white anymore.Both white tea and green tea did not gave something interesting.The one with blueberry gave something with a touch of purple or pink but really pale.Matcha looks like a dirty green which is not great.Rooibos gave a pale orange and the same thing for black tea with roses.Orange pekoe and instant coffee gave a darker orange.Roast chicory gave a medium brown when it dry.

What did I choose to use
For the costume of my son I use a mix of instant coffee and roast chicory for the pant.The first time the color wasn't uniform, it was pale near very seams.I put it under running water .I get something more pale but more uniform this time.
For the tunic , I finally try to use blue dylon dye .I choose a cold dye and use 3 capsules of it.Like I said before , the fabric was blend which I know wasn't the best to make serious test.Anyway , I did get a pale and soft blue as a result.I would prefer a darker tone of blue but I'm ok with this one and both color are ok together.
Darker tea gave a more interesting result.It was nice to try this and yes I could do it again.Who ever said dye have to be permanent.Next time i'm going to try with differents fabrics and stains.
