I saw another blogger make a fabulous Armour of God felt book activity, but unfortunately don't know what blog so can't post credit (sorry).
A4 design, the soldier without his armour.
I've created a couple of versions, all of which can be printed onto card, laminated and made into a great scripture related activity. It can also be printed on to transfer paper (if using a mirror image version of image.
The pieces can also be matched to the correct shape/ word.
