Bought a blender and blended the rosehips, wouldnt blend properly though so I had to add oil to them. The end was result was far from what i was hoping for, in terms of colur. It came out much darker and had the appearance of mashed up sick or soup. Carried on anyway in the name of experimentation and slathered the mush onto the studio wall with a ruler. Next I collected some elederberries from behind the studio, crushed these up and painted them on with my fingers. Good fun and an iteresting effect but not what I was hoping for.
