Water soluble paper - which I have used to print on many times and to stitch on and wash out parts etc etc - then I came across a video made by Liz Kettle water soluble transfer using the paper to transfer images using a gel medium and I thought I would try it - I have seen it used to transfer images to soap whihc has fascinated me but as I don't make soap I haven't tried it. But I did try a few a while back and I wasn't happy at all with my efforts - maybe I was expecting too much. However the other day I decided to give it one last shot. The above is one of my pohutakawa photos and it mostly worked except right in the middle where the paper lifted but I can work around all of that.
Next I tried a few more and I am pretty happy with most of these - above is me in Marrakesh and it is possibly the most successful.
