We were sent the AirBrainz™ airbrush line from Testors® including assorted paint colors, and blank sheets for creating our own stencils to try out. It was so much fun.
We decided though that the most kid-friendly way to do this was to use some of our fun craft punches on the stencil sheets. These have a sticky back, so when you punch the stencil, simply peel, stick, and you are ready to spray.
