Sorry, I am really late in this reply!!! Just found this thread.
Here is a 'recipe' for practically indestructible bread dough ornaments that I used with great success in school craft classes.
It actually uses bread as the base. You take one slice of white bread (stale is fine) - and cut off ALL of the crust. For each slice of crustless bread you use one tablespoon of white/craft/school glue. Tear a slice of bread into small pieces. Using your hands, mix in a tablespoon of glue. (For each bread slice add a Tbsp. of white glue). This is a terribly messy procedure - maybe why it is fun?
Keep working the bread/glue until it forms a smooth elastic dough.It sticks to your fingers for awhile. (Lots of 'eeews' and 'yucks' if you are teaching a class!)
When it is workable, divide it into smaller amounts. Then you can add tiny amounts of paste foodcolour to each bit (sometimes a toothpick tip of paste colour is enough. Paste food colour is available in most grocery stores). This eliminates the need to paint your ornament later.
Shape your dough into whatever your imagination comes up with. We have Santa, penguins. snowmen, gingerbreadmen, elves, holly, angels and Christmas balls.
If you would rather, don't colour your bread dough. It will air dry and you can paint it later.
We have had some of our favourite ornaments for more than 20 years. As I said, they are almost unbreakable.
Have fun!
