We made the wearable Helmet of Salvation available at craftingthewordofgod.com.  There are two sizes available–adult and child.  My son is modeling the child-size helmet here.  I tried out the adult size on myself, and it fit just fine.  This craft is good if you have an extended period of time, but would be a real challenge if you have a limited amount of time.  There’s quite a bit of coloring and cutting, then fitting the pieces together and stapling.  So…it’s an awesome craft, but make sure you have the time to do it.
