Painting with flowers

In this experiment I’ve died an old silk dress with leaves of flowers and other plants. Unfortunately not many colors remained except for the yellow of the curcuma root. First I sprayed some vinegar mixed with water onto the fabric and than I placed some flowers leaves onto the fabric, made a bundle of it and let the fabric steam for some time. 
During the fair fashion event in Utrecht I’ve died some fabric with leaves, onions and avocado skin.
