Now this looks like real fun. I must give this a try.
This is a finished small quilt where maker Terry Whyte of Canada placed textile paints on 1 side of an opened up sheet protector.. then foldered closed the sheet protector and reopened it having roughly the same paint pattern on both sides. She placed a piece of fabric atop the symmetrical painted surface to create a monoprint. Once the print was dry, only then did she decide to turn it into a butterfly, cutting away/discarding the unneeded monoprinted fabric. SO clever!
