First I put some colour (fabric paint) on a glass printing plate. Note the lovely design on the fabric covering Marlene's work area from previous experiments!
I didn't throw the leaves away, but picked them up with tweezers and placed them, painted side down, on another fabric. I brayered over them to transfer that paint to the fabric beneath. So I now have positive and negative images of those leaves!
Next, I washed off the plate and brayered some new colour onto it. I used a chopstick to incise a design in the paint.
