Salt Dough Ornaments

We made ornaments for on our tree, ones that weren't collectible, ones that weren't very breakable, ones that if they didn't last to see next year we didn't really care. We made them out of salt dough. (recipe here)  We mixed them up, rolled them flat and cut them out.

 The recipe said you could speed the hardening process by 'baking' them at 200 degrees for about 20 min. Ours 'baked' for about 2 1/2 hours, then sat out all night and were still not really hard the whole way through the next day... I wonder what we did wrong?

 

Regardless of their soft middles we painted them the next day... 

ok - Nick ate one. (pre-paint) I didn't think he'd like it.

He ate the whole thing.
