I enjoyed playing around with the leaves and bleaching them onto fabric, I think it worked even better than doing it on paper, more like doing it on tissue paper and removing that colour. I created a dyed green fabric and decided to bleach this back and see if it just removes the colour.
The method for this is to use a SYNTHETIC brush (I learnt my lesson after my natural bristle brush ended up without any bristles left) and paint the back of the leaves using bleach, I have used bleach and a bleach-water mixture, they both seemed to do the same just I think some fabrics could not handle the undiluted bleach. I then printed these leaves onto the dyed fabrics and flattened it with a book to get an even spread. Then removed the leaf and watched it develop. They actually turned quite orange which I did not expect but the effect of it is good.
