Help me please.

I'd like to make some handprints in salt-dough, which can then be made into little Mothers' Day gift plaques by hardening, painting and varnishing.

I've no idea where to start.

Is there a good recipe for salt-dough which will hold the print and dry hard? Do I air-dry the dough or bale it to harden it? How? (Bloke alert: if this involves an oven, I need to know the temperature setting, bake time, etc.)

Anything else I need to consider?

Thanks.
