Sgrafitto is like when we were in kindergarten and we colored a sheet of paper with colored crayons then crayoned over it all with black and used a penny to scrap away the black revealing the colors below. Does anyone remember that??
Well, in this case the first layer is painted on with acrylics. When they are VERY dry, I covered this first page with white then used a tiny piece of bookboard and the end of a paint brush to scratch away the white revealing the colored layer beneath.
I REALLY love the way this "winter landscape" came out.
This next one I painted then over painted with black to try to bring the images together.
I felt this was successful too.
This could be done on fabric with reverse applique.
