We've been studying the armor of God this past week. The boys already have various pieces of plastic play armor but they didn't have breastplates. So on that day we practiced tracing and painting our own breastplates. They first had to choose what design they wanted (diagonal or straight stripe etc.), then they chose their colors and painted. The next day they used glitter paint (very good handstrengthening activity) to add details to their breastplates. You'll see pictures of the complete armor when it's all finished.
The Little Sweetie wasn't really interested in painting hers until I squished a bunch of paint directly onto her breastplate and let her fingerpaint! Perfect!
