Paint on Foil Tape Resist

I wrapped a piece of cardboard with aluminum foil and used painter's tape to create a tape resist for Kate to paint.

 She asked me to paint with her, and I did, but she did most of the painting herself, and often when I painted an area, she didn't agree with my color choice and so she painted over it with another color!

Here is her piece after she finished painting:

After her nap, the paint was dry, and we peeled off the tape.

This is her finished masterpiece!  Beautiful!
