Here's how we did it:
First Matty printed several copies of his message & glued it on construction paper. Next we covered the message with strapping/packaging tape. Then mixed together 2 parts acrylic paint + 1 part Dawn dishwashing liquid. I painted over the taped message & let it dry. These were our practice strips to make sure it worked.
We waited one hour before testing the paint. Success!
|I got a little carried away with my sponge brush. The paint around the message|
was way bigger than it should've been. Oh well.
My fix: add cute stickers...
