If you're fed up with ordinary playdough, here is an alternative that you could try !!
Oatmeal & Custard
A can of ready cooked custard
Rolled oats!

Mix the two together to form a mouldable dough.

Edible, this dough is fantastic to use with the younger ones who may still be at the mouthing stage !

Use flour or icing sugar as a table covering as the dough can be sticky.
